Problem : System error 87 has occurred. The parameter is incorrect while mapping a drive

I have a W2K Server running Citrix Metaframe 4.0  – SP4 and most patches.
About a week ago we started getting the following error when users scripts run:

net use j: \\serername\sharename
System error 87 has occurred. The parameter is incorrect.

When we try to map via Windows we get:
“The mapped network drive could not be created because the following error has occurred:
Attempt to access invalid address.”

If I reboot in Safe Mode with Networking I am able to map drives.
This is affecting ALL users and is critical.  ** Please give me some pointers – I’m fresh out **

I have opened up a MS ticket but they have been of little value.
Additionally, MS products are ‘dumping’ on occasion.

All of those are shared and with permissions granted ?

And if you try ” Net use \\servername\share /USER:username ” ( It asks for the password later on)
Try the above with domain user and Local Admin user !
