Bluse screen in mup.sys after SP4

[SUO]

Hello,

I get a blue screen when i map a drive of my computer since i've installed W2K_SP4.
The dump is like that :

stop : 0x0000001e (0x0000 ....) KMODE_EXCEPTION_NOT_HANDLED address BF... in Mup.sys

I could reproduce the pb at any time.

Any idea ?
Thks in advance.

I have done sum research and i have found the following that might be of help to you

• We're using Win2K workstations in a network with a Microsoft Small Business Server (SBS) 4.5 server and a Win2K server. After we installed SP4 on some workstations, they all started to produce a blue screen, with the message Stop 0x00000001e (0xc00000005,0xbfeaed16, 0x00000000, 0x00000000) KMODE_EXCEPTION_NOT_HANDLED Address: bfeaed16 base at bfeae000, datestamp 3e25bc59 - mup.sys.
• The Microsoft article "List of Networking Fixes in Windows 2000 Service Pack 4" (

http://support.microsoft.com/?kbid=815023)

explains that SP4 replaces mup.sys to solve a buffer overflow security vulnerability. I've seen articles in several newsgroups linking this problem with the Novell client. In the past, we've used a Novell server, and therefore a Novell client was installed on these systems. We uninstalled the Novell client and shut down the Novell server. Today, I found the following post in the newsgroups:

”There's a problem with the mup.sys in SP4. As a temporary workaround, set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mup\DisableDFS to 0. This gets rid of the blue screen." Microsoft is supposedly working on a fix (updated MUP) according to another poster. I haven't been able to test these solutions because we uninstalled all SP4 installations.
