pmol -> MP is not responding to HTTP requests (3/24/2004 7:42:11 AM)

Hi,

I have 2 Primary sites and 13 secondaries, but for one secondary site I can' t get the MP running, the following status messages appears:

MP Control Manager detected MP is not responding to HTTP requests. The http error is 12152.
Message ID : 5436

I have read some documentation which says it must be the site server to SQL server connection, but so far I haven' t had luck.

All (virtual)folders have been made in IIS, including the SMS_MP, so it doesn' t seem to be a problem with IIS.

Anyone a suggestion ?

thanks

Have you setup the proper security (i.e. local groups and machine accounts)??

Check out this article: http://www.myitforum.com/articles/8/view.asp?id=6838



pmol -> RE: MP is not responding to HTTP requests (3/24/2004 1:03:24 PM)

Hi,

I did setup the proper permissions, I am running advanced security and all site server computer accounts are member of a group which is member of domain admins.

Almost all other sites are functioning right so I guess the permissions are setup right.

@lhedding

Thanks for the link, I' ll check it out and let you know when I figured it out.



rfellows -> RE: MP is not responding to HTTP requests (3/24/2004 11:12:02 PM)

Did you check the MDAC version? Assuming you have all the premission in order. This is the last thing I would check.



pmol -> RE: RE: MP is not responding to HTTP requests (3/25/2004 7:06:31 AM)

Hi,

I have just checked it and it is running v2.5 sp1 which is not the same version as other sites, going to update after work hours.

Could this be a problem ?

From which version is it supported ?

thanks



lhedding -> RE: MP is not responding to HTTP requests (3/25/2004 7:11:33 AM)

Yes, it could be the problem. For some reason any version of MDAC less than 2.8 has the possiblity for issues. Try to update MDAC to this version.



pmol -> RE: RE: MP is not responding to HTTP requests (3/26/2004 12:58:07 AM)

Hi,

Still problems with my management point, the following status messages are logged in SMS:
_______________________________________________________
MP Control Manager detected MP is not responding to HTTP requests. The http error is 12152.

Possible cause: MP service is not started or not responding.
Solution: Manually restart the SMS Agent Host service on the MP.

Possible cause: IIS service is not responding.
Solution: Manually restart the W3SVC service on the MP.

Possible cause: MP encountered an error when connecting to SQL Server.
Solution: Verify MP can connect to the SQL server and has sufficient access rights to the SQL server site system.

Possible cause: The Default Web Site is disabled in IIS.
Solution: Verify that the Default Web Site is enabled, and functioning properly.
_______________________________________________________

When you look at the installation of the MP it is installed fine, as you can see in the log below.
______________________________
MPsetup.log

______________________________

I did have some problems before with the SMS Agent host which had the status " disabled" and I could set it to automatic and the service started again. But no other problems detected.

When I go the the URL for testing the MP it says " ERROR" in the header of the Internet Explorer.
http://<servername>/sms_mp/.sms_aut?mplist

any suggestions what it could be ?

Running Advanced Security? If so, is this site system machine account in the SMS_SiteSystemToSQLConnection group? After putting the secondary site server in this group you might need to reboot the server to get the new security principles associated with the machine account.

Is IIS working and running properly?



pmol -> RE: RE: MP is not responding to HTTP requests (3/26/2004 7:36:10 AM)

Yes, I am running advanced security.

The machine account is member of the SMS_SiteSystemToSQLConnection group.

IIS is running fine, and in the MPSetup.log file it says that the MP installation has finished Successfully.

probably another suggestion ?

thanks



lhedding -> RE: MP is not responding to HTTP requests (3/26/2004 7:49:16 AM)

Have you rebooted the secondary site server after putting the secondary site server machine account in the SMS_SiteSystemToSQLConnection group?



djames392 -> RE: MP is not responding to HTTP requests (3/27/2004 12:56:13 AM)

It is more than likely a SQL login failure. (I' m concluding this because all other secondaries are working; and the MP installation was successful.)

The easiest way to figure this out: Run SQL profiler on the site server, and add security events to the trace. Then hit the Secondary site MP with the test URL: http://<servername>/sms_mp/.sms_aut?mplist

Look to see if SQL is getting a login attempt. If it is, check to see the security context.

My guesses:
1) The secondary site is in an NT4 domain; thus has no machine account context (except anonymous)
2) The secondary site is cross forest from the SQL box, and you aren' t in a W2K3 domain w/ cross forest trusts set up. Thus the machine account context is anonymous.
3) The secondary site cannot authenticate Kerberos to the SQL machien, (Thus the connection is anonymous.)
4) The secondary site machine account is not included in the SiteSystemtoSQLConnection Group. (You already checked this.)
5) The SQL server is running under user context, instead of local system - and its SPN isn' t registered correctly in AD.
6) The SQL server is in a different domain than the secondary site, and it' s SPN isn' t registered correctly in AD.

1-3 all show up as an anonymous connection in SQL profiler.
4 shows up as an access denied.

pmol -> RE: RE: MP is not responding to HTTP requests (3/27/2004 2:25:40 PM)

Hi,

Thanks for your comments,

I am going to try the SQL profiler and see if I can trace the problem.

All servers are on Windows 2000, only 1 forest and the machine account is in the SiteSystemtoSQLConnection group.

Other secondary sites are also reporting to the same primary (and SQL) server, so I would say the SQL server is running as it should be.

All servers belong to 1 domain.

I' ll post the information I get from the SQL Profiler when I ran it.



phejmanowski -> RE: MP is not responding to HTTP requests (3/27/2004 4:22:21 PM)

Did you try MP Spy in the toolkit...?



curban -> RE: MP is not responding to HTTP requests (3/27/2004 6:04:17 PM)

FWIW... The site server machine accounts need to be in the SMS_SiteSystemtoSiteServerConnection group as well. I' m not sure if it has bearing here or not... but a requirement, none the less...

Chris



pmol -> RE: MP is not responding to HTTP requests (3/28/2004 1:26:53 PM)

I didn' t try MP Spy yet, within 10 hours my weekend is over and I' ll try it.

Post the results here.

thanks for the information

by the way, all site server accounts are member of SMS_SiteSystemtoSiteServerConnection.




pmol -> RE: MP is not responding to HTTP requests (3/29/2004 5:39:10 AM)

Hi,

I have run the SQL Profiler, with the security options added, but I don' t see any logon for the server which has a problem with it' s management point.

I do see all other MP servers logging on, but the one with a problem.

what else can I do to find the problem ?

thanks



lhedding -> RE: MP is not responding to HTTP requests (3/29/2004 6:58:01 AM)

You are running MDAC 2.8?

SQL boxes that are running under a user account, instead of system, need the SPN updated in AD. Read the readme_operations.htm from the root of the CD for info how to do this. This article also has info this topic: http://support.microsoft.com/default.aspx?scid=kb;en-us;829868



pmol -> RE: RE: MP is not responding to HTTP requests (3/30/2004 12:55:31 AM)

Hi,

Yes I am running MDAC v2.8 and the SQL server is running under " System" , so I guess the SPN doesn' t have to be updated.

anything else I could do ?

thanks




brogers -> RE: MP is not responding to HTTP requests (3/30/2004 1:30:31 PM)

" other mp servers" how many do you have?

Is this one not for the primary site? but for a child?



ctimberlake -> RE: MP is not responding to HTTP requests (3/30/2004 2:03:33 PM)

if you find out the answer to this, please let me know....I have the same problem on two. I have been on the phone with Microsoft back and forth for 3 days, and they cannot figure it out either. I can uninstall the mp, uninstall iis, reboot, reinstall iis, reinstall mp, and it will work for a couple of days, or until the server is rebooted, then it stops working again....keep in touch and I will let you know what I find out....I am running in standard security, with 2003 servers, and having the almost exact same trouble, posted up above, but no responses.......



pmol -> RE: MP is not responding to HTTP requests (3/31/2004 12:34:29 AM)

Hi,

I have 2 Primary and 13 Secondary site servers.

At both Primary servers and 12 out of 13 Secondary site server it it working fine.



brogers -> RE: MP is not responding to HTTP requests (3/31/2004 12:35:51 AM)

Id check for a service on that machine that is disabled..or not starting properly!



pmol -> RE: MP is not responding to HTTP requests (3/31/2004 1:12:06 AM)

I have done that, all services seem to function right.

Would it be an option to remove the MP and IIS from the server and try it again ?

I don' t think it will help since the MP is installed successfully but only the MP is not responding to HTTP requests.

The SMS Agent Host service had a status of " Disabled" some time ago, I enabled it again and started the service,

I don' t know if this could be a problem.



brogers -> RE: MP is not responding to HTTP requests (3/31/2004 1:50:08 AM)

That is certainly a related service!

How did it become disabled? someone manually had to do it.



pmol -> RE: MP is not responding to HTTP requests (3/31/2004 2:35:44 AM)

Probably an administrator of that site server has done it,

the organisation is quite big and we have more that a few administrators.

But it doesn' t matter for now, I have enabled it again a week ago, and the problem is still there.



brogers -> RE: MP is not responding to HTTP requests (3/31/2004 3:04:31 AM)

Is anything else disabled or set to manual that normally should be started?



pmol -> RE: MP is not responding to HTTP requests (3/31/2004 4:51:44 AM)

No,

I have checked all services, and everything that is needed is running.

The error I get is mentioned below, so the MP is running but not accepting HTTP requests, what else could it be ?

MP Control Manager detected MP is not responding to HTTP
requests. The http error is 12152.



ctimberlake -> RE: MP is not responding to HTTP requests (3/31/2004 11:05:42 AM)

I was able to resolve my trouble (temp) by uninstalling the mp, wait until the mpcontrol.log said uninstall successful. Then on the secondary site server, uninstall all items related to iis, including bits, asp,www,webdav, and etc. Then reboot the server. When back up install all on secondary server, then enable mp on primary site. Watch the mpcontrol.log until it says successful as bottom line. Then try the \\servername\sms_mp\.sms_aut?mpcert and mplist and they will work.

My trouble comes when someone reboots the server, it will not connect, I have to keep repeating this process over and over. And Microsoft hasnt figured it out either/?????



jovecka -> RE: MP is not responding to HTTP requests (3/31/2004 11:26:18 AM)

Do you have a group policy that could be refreshing when you restart?



ctimberlake -> RE: MP is not responding to HTTP requests (3/31/2004 11:29:25 AM)

just the default policy, that hasnt been tampered with... It is just this one secondary server out of 13.....



brogers -> RE: MP is not responding to HTTP requests (3/31/2004 12:44:48 PM)

Well..you have managed to stump us..and PSS...thats a whopper of a problem there Chris...I really am sorry I cant be of more help :(



ctimberlake -> RE: MP is not responding to HTTP requests (3/31/2004 12:48:02 PM)

I know, not much get by you Brian........oh well, the good folks at microsoft will eventually help me...... :)
