SP3 and VMS/Pathworks/LanManager Drive Mapping

Re-load service pack two or contact Microsoft to report the bug!
Oh, and don't load it on any other machines that may need to do this.

Thanks for the suggestion, but your suggestion is pretty much a no brainer.  I haven't installed SP3 on any other machines since we bacame aware of this problem, although there is a pressing need to do so to solve some other problems that SP3 does address.  Microsoft is aware of the problem, but I have yet to hear a response from them.  The problem seems to lie within the new security measure included with SP3, and is probably set with from inside the registry, but so far no one has been able to suggest what needs to modified.

To be honest you didn't ask how to modify the settings of the registry so the insult was not needed (ask a no brainer question get a similar answer). If you stated earlier what you have stated above I could have formulated a better answer for you.
I'll go and do some research & if I get an answer I'll come back to you.

The implication of an insult was assumed, I forgot that this is via the internet where flaming is a way of life.  No insult was intended by me.  I assumed that since I was asking a fairly high level question of experts, delving into too much detail would be time consuming and unnecessary.  The actual message that returns from Windows NT is .... The account is not authorized to login from this station.  

Daniel, the answer you gave does answer part of another problem I have been seeing, however I have been able to fix the problem.  After looking around in the Microsoft Knowledgebase I discovered "Q166730"  titled "With Unencrypted Password SP3 Fails to Connect to SMB Server"
It gives instructions on modifying the registry to enable plaintext passwords to be sent to "Old LanManager SMB Servers"  thanks for the information on the other question I had not submitted yet.
