SBS 2003 to 2008 Migration Stall – Event 1001 SBSSetup.exe and CLR20r3

This one is a stumper.

The migration is from SBS 2003 to SBS 2008 with approximately 45 users and a 45GB mail store. Most of the users are remotely connected.

The error in the SBSSetup.log:

[4020] 090520.201958.9605: Setup: Exception removing info: System.IO.IOException: The process cannot access the file 'C:\Program Files\Windows Small Business Server\Data\info.xml' because it is being used by another process.

   …Microsoft.WindowsServerSolutions.Setup.SBSSetup.MainClass._PrepareForFinalExit(Boolean stillHaveOneMoreReboot)

[4020] 090520.202756.1849: Setup: Removed SBSSetup from the RunOnce.

The error in the SBS 2008 Event Log:




CLR20r3 with System.IO.IOException

We just ran the migration on our own hardware by having our client ship us a ShadowProtect image of the source server that we used to complete a Hardware Independent Restore to one of our lab servers.

We used one of our own quad core Xeon 3000 series boxes to run the SBS 2008 setup in Migration Mode on.

The failure is always during the DCPromo and Active Directory replication cycle of the SBS 2008 Migration Mode install.

At this point, we are completely stumped and are looking to get Microsoft support involved to figure out where the problem lies.

Hopefully when we find the solution to the problem, we will post that here.

Note the following:

  • Okay: NIC binding order
  • Clean: DCDiag
  • Clean: NetDiag
  • Clean: RepAdmin /SyncAll
  • Clean: RepAdmin /ShowReps
  • Clean: ADSIEdit.msc of any other DC references
  • Clean: ntdsutil in MetaDataCleanup mode
  • Clean: Active Directory Sites and Services
  • Clean: SBS 2003 Best Practices Analyzer
  • Clean: Migration Preparation Tool on SBS 2003

UPDATE 2009-06-02: A support incident has been opened with Microsoft’s Product Support Services to get this resolved. Hopefully we can.

UPDATE: 2009-07-10: Workaround found: SBS 2003 to 2008 Migration Stall – Event 1001 SBSSetup.exe and CLR20r3 – Workaround Found!

Hi, I am stuck with this problem too. Today I was migrating from sbs 2003 to sbs 2008 and when the migration wizard appears it's hanging after 20 minutes and then I get the message "Setup has stopped working" with the event CLR20r3. Hopefully there will be a resolutiom soon.

Please zip up the entire Logs folder on the SBS 2008 server and e-mail it to me. Link on the right for e-mail.

Any solutions on this issue yet?

No, at this point we are setting aside some time to work with the Microsoft Product Support Services team to find a resolution.

Just wondering if this was ever resolved. Starting a sbs03 to sbs08 migration myself next week :)

The post has been updated with a link to the workaround Microsoft came up with.

The source of the problem was updates being delivered via WSUS on the source server having a high priority deadline that forced them to download and install automatically.

Disabling WSUS on the source server before starting the migration process is the best way to protect from this particular problem.

Just in case, here is the link: SBS 2003 to 2008 Migration Stall – Event 1001 SBSSetup.exe and CLR20r3 – Workaround Found!.
