Post SP4 connection to DOS problem

[Mark D]

I have two Machines set up as follows:
PC1 is a DOS Peer Server
PC2 is a Win2k Server

Prior to the SP4 Upgrade on PC2 both machines were able to
communicate.
After the upgrade, PC2 cannot map a drive to PC1.
(net use * \\pc1\xxx).

1.I have confirmed that this is due to the upgrade
2.I cannot uninstall SP4
3.I do not want to rebuild PC2

Any Ideas ?

Windows 2000 server is probably set for SMB signing. On PC2, open Local
Security Policy (under Admin tools), select Local Policies, security options
and then set these two policies to disabled:
1. Microsoft Network server: Digitally sign communications (always)
2. Microsoft Network server: Digitally sign communications (if client
agrees)
Also change the similar policies under Microsoft Network client.
