SSO/Biztalk Service fails to start after applying .NET 4.0

SSO/Biztalk Service fails to start after applying .NET 4.0

  • Comments 2

Recently we noticed an issue with ESSO with .NET 4.0 that could potentially affect Biztalk and HIS customers.  We have released an update for ESSO on DLC along with a KB explaining the issue.  The fix is also scheduled to go on the upcoming Microsoft Update. 

SSO service fails to start after applying .NET 4.0. This is caused by a missing assembly registration entry in the SSO installation.  The assembly is bound to CLR 2.0 but there is no specific entry for this requirement.

 SSO is a required service for Biztalk and HIS and hence these services also would fail to start.

 This issue can also be repaired by using the regasm tool to re-register the SSOSQL assembly. Regasm.exe is included with the .Net Framework.

32-bit Server
1.       Open a command window
2.       Go to C:\Windows\Microsoft.NET\Framework\v2.0.50727
3.       Type: regasm “C:\Program Files\Common Files\Enterprise Single Sign-On\ssosql.dll”

64-bit Server
1.       Open a command window
2.       Go to C:\Windows\Microsoft.NET\Framework64\v2.0.50727
3.       Type each of the following and hit ENTER:

32bit:  regasm “C:\Program Files\Common Files\Enterprise Single Sign-On\win32\ssosql.dll”
64bit:  regasm “C:\Program Files\Common Files\Enterprise Single Sign-On\ssosql.dll”

Note On a 64-bit server, regasm will need to be run for both the 32-bit and 64-bit versions of ssosql.dll.

Thanks

  • Hi

    Is there now an package hotfix for this? We use BizTalk 2006 and it would break our accreditation criteria to apply a unofficial fix. This means we can't move to .NET 4.

    Many thanks
