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

  • Article

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
