Connecting Enterprise manager to SQL 2000

Hi !
I'm running SQL Server 2000 Dev on Win XP Prof and having problem connecting
via Enterprise manager, getting this error in Event-logg:
17310 :
FRunCM: Process 3084 generated fatal exception c0000005 EXCEPTION_ACCESS_VIO
LATION. SQL Server is terminating this process.
When connecting via SQL Query Analyser everything works fine.
When connecting my Enterprise manager to other SQL-servers everything works
fine also.
I've tried both Named pipes, TCP/IP.
My database is having SP 2 but I'm getting an error in sp3_serv_uni.sql when
trying to
install SP3A...
Regards,
FredrikCheck the network libraries at the following registry location.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MS
SQLServer\MSSQLServer\SuperSocketNet
Lib
Verify that the service account starting SQL has correct registry and file
permissions.
