Microsoft BizTalk 2009 and Enterprise Single Sign-On was running smooth on all the machines and after more investigation the following error was caused by an automatic update of Microsoft .NET Framework 4.0.

Windows could not start the Enterprise Single Sign-On Service service on Local Computer.
Error 0x80131700: 0x80131700
---------------------------
OK
---------------------------
After looking in the event viewer I was getting the following error:
Could not create SSOSQL. To fix the problem, reinstall SSO or try 'regasm SSOSQL.dll' from a Visual Studio command prompt.
Error Code: 0x80131700
The solution was to register the assembly SSOSQL.dll with the following command:
regasm C:\Program Files\Common Files\Enterprise Single Sign-On\SSOSQL.dll
Please be caution if you're running under 64-bit you must make sure you are in the Framework64 directory (C:\Windows\Microsoft.NET\Framework64\v2.0.50727) when executing the above command.
