Distribution Manager in System Center Configuration Manager 2007 is blocked by checking distribution points and packages

RAPID PUBLISHING ARTICLES PROVIDE INFORMATION DIRECTLY FROM WITHIN THE MICROSOFT SUPPORT ORGANIZATION. THE INFORMATION CONTAINED HEREIN IS CREATED IN RESPONSE TO EMERGING OR UNIQUE TOPICS, OR IS INTENDED SUPPLEMENT OTHER KNOWLEDGE BASE INFORMATION.

After you do a site reset by using System Center Configuration Manager (ConfigMgr) set up or you do a hotfix installation with a site reset, Distribution Manager needs hours to check following things if the sites have many distribution points and thousands of packages on the distribution points.

Cause 1

Setting SigURL / Setting HTTPUrl for every package on every distribution point.

 

The following is an example from DistMgr.LOG file:

 

1/27/2009 14:52:58          Setting HTTPUrl to http://JENSGOPALSRV001/SMS_DP_SMSPKGC$/HP100005/ for package HP100005 on DP \\JENSGOPALSRV001\SMSPKGC$           628 (0x0274)

1/27/2009 14:52:58          Setting SigURL to http://jensgopalsrv001/SMS_DP_SMSSIG$/HP100005.2.tar for package HP100005 on DP \\jensgopalsrv001\SMSSIG$          628 (0x0274)

1/27/2009 14:52:58          Setting HTTPUrl to http://JENSGOPALSRV001/SMS_DP_SMSPKGC$/HP100009/ for package HP100009 on DP \\JENSGOPALSRV001\SMSPKGC$           628 (0x0274)

1/27/2009 14:52:58          Setting SigURL to http://jensgopalsrv001/SMS_DP_SMSSIG$/HP100009.2.tar for package HP100009 on DP \\jensgopalsrv001\SMSSIG$          628 (0x0274)

 

Cause 2 

SMS_Site_Component_Manager creates a RESETISAPI.TRN in the INBOXES\DistMgr.BOX directory if a real site reset is initialized by ConfigMgr Setup / Hotfix Installation / "PREINST /StopSite" or a site upgrade happens.

 

Note Site Reset is initiated by via SHUTDOWN.TRN created in directory INBOXES\SiteComp.BOX, a Site Upgrade via RESETALL.TRN.

 

The following is an example of the DistMgr.LOG file:

Note In both causes, the SMS_Site_Component_Manager creates a RESETISAPI.TRN.

Resolution for Cause 1

This issue is addressed by hotfix KB956194. For more information about hotfix KB956194, see the following article in the Microsoft Knowledge Base:

 

956194 Distribution Manager in System Center Configuration Manager 2007 Service Pack 1 may require several hours after startup before it begins to process packages

 

Additionally, registry changes are necessary to disable the verification that Distribution Manager runs on distribution point properties at startup.

 

HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\Components\SMS_DISTRIBUTION_MANAGER 

 

Create the following new value:

 

Name : DoNotVerifyDPPropertiesOnStartUp

Type : REG_DWORD

Value : 1

 

Note This will disable the verification that Distribution Manager runs on distribution point properties at startup.



 

If the DoNotVerifyDPPropertiesOnStartUp item does not exist or if its value is set to 0, Distribution Manager will verify distribution point properties during the startup process. If the value of the DoNotVerifyDPPropertiesOnStartUp item is set to 1, this verification behavior is  disabled.

 

With hotfix KB956194 and the registry changes completed, you should find only following line in the DistMGR.LOG file:

 

1/27/2009 14:57:43          Skip DP Properties Verification. 2892 (0x0B4C)

Resolution for Cause 2

You can prevent such a scan if you delete RESETISAPI.TRN before SMS_Distribution_Manager can pickup the file - rename distmgr.dll to distmgr.org before the site reset happens.

 

If the site reset finished by SMS_Site_Component_Manager and you have delete the TRN, rename back the DLL and restart SMS_EXECUTIVE.

 

Note You can upgrade SMS hidden file ISAPI on all BITS enabled distribution points for example over night by creating RESETISAPI.TRN in INBOXES\DistMgr.BOX directory.
