How can I install NetBEUI in Windows Server 2003?

note to above post, performance was bork due to cabling issues.

Had similar security issues as several ppl here, and found a fix to the "access denied" problem.

Changing these settings in Domain Controller security
Local Policies -> Security Options ->
"Microsoft Network Client: Digital Sign Communications" Disabled
"Microsoft Network Server: Digital Sign Communications" Disabled
this applies to both the "(Always)" and "(if server/client agrees)".

HOWEVER, an network operation that took 15 seconds with Windows 2000 WS, takes 5 minutes completing with the Windows 2003SBS server.

Anyone had similar issues, and found a solutions ?

Within the 2003 server enable Netbios over TCP/IP. In OS/2 MPTS Network Adapters add the protocol IBM OS/2 Netbios over TCP/IP, change the Netbios number to 1, set TCP/IP and IBM OS/2 Netbios over TCP/IP to 0.

Modify the ibmlan.ini file..
[networks]
net1=NETBEUI$,1,LM10,100,121,14
net2=TCPBEUI$,0,LM10,100,121,14

Hopefully I will get someone with a solution to my problem.
We have some OS2 ver 3 systems working with an NT server.
We want to upgade to Server 2003. I have a new server, loaded 2003 and also loaded NetBUIE on it.
When the OS2 tries to connect to the server it comes up with passord error. I know th password is correct.
Any ideas what it could be the reason?
Thanks
