Hi all,Currently I have 2 windows servers (both DCs), one is 2003 R2 with SP2, other is 2003 SP2, with Exchange 2003 SP2 installed on one of them. Schema master is R2 SP2.Forest and domain has Windows 2003 functionality, Exchange - native.When I run Exchange setup, I have prereqs failed, with: Error: The schema master is not running Windows Server 2003 Service Pack 1 or later.Error: Cannot find at least one global catalog server running Windows Server 2003 Service Pack 1 or later in the local Active Directory site.I did all dcdiag, netdiag, replmon - everything I can think of, and it looks good. The only thing is - both DCs arePolish and have locale set to Polish, however I'm not sure if this is relevant. I found this:http://support.microsoft.com/kb/919166but it will not install, it says newer update is already installed.Any input would be appreciated.

I found solution, looks like there is bug with BPA, at least with Polish versions of Windows. Versionvalue is beeing compared with LDAP search resoult for: CN=DCNAME,OU=Domain Controllers,DC=firma,DC=sa and Attribute: operatingSystemServicePack In EN version it has Value "Service Pack 2" in POLISH it has Value: "Dodatek Service Pack 2" WORKAROUNDsimilar to Exchange Article 827784 "0XC007FFFF (65536): An Unknown Error Has Occurred" Error Message When You Run Exchange Server 2003 Setuphttp://support.microsoft.com/default.aspx?scid=kb;EN-US;827784there is already a workaround proposed by changing the OperatingSystemServicePack attribute manually with ADSI to the needed value.

Thanks for yours sharing here.Regards,Xiu
