I am trying to connect from win XP clients to a novell Netware 6.5 sp3 server that untill today had been acting fine.  When I try to log in I get the error above.  None of the workstations that have rebooted can log on all that have not are still loged on fine.  Where do I start?

Start here...
Also, what does 4.9- mean? Is it 4.90 or 4.91? Try client 4.91sp2. Also, you should install SP5 on your netware server.

Are you running NMAS?
If not go into Novell client properties ,advanced settings .pull down menu, and turn it off.

Just for the heck of it ,have you looked on your server console for an error or abend?

The suddenness bugs me a bit.  That it coincides with "patch tuesday" bugs me more.

Do you have WSUS or are you getting your Windows updates via autoupdate directly from the M$ site?  If it's WSUS you may want to be more careful with testing before you approve the hotfixes...

Not saying that it was a "patch tuesday" issue, for sure, but if nothing else changed, and there are no abends or errors on the server, that's what I'd suspect first - especially if things are working 'til you reboot the client PC.

More on "patch tuesday" - I haven't checked yet to see what all they pushed out this go-around, but I understand there were like 8 critical updates.  I will look into it more in-depth now and post back (if I remember) with whether there are any that I think might be suspect for this issue.

Oh,wouldn't that be just dandy!

And do you know what would make it even more interesting?
If the "NEW" WGA download ( deemed a critical patch ,even though it is pre-release software and not critcal to anybody but M$))were the culprit.

Shades of the Sony DRM scandel!

MS06-025 RRAS vulnerability fix may be a possibility, as it affects RPC login activities.  Then there's MS06-031, also affecting RPC authentication, but that only affects W2KSP4.  Then there's MS06-030 SMB hotfix.  Ii don't see how the TCP/IP hotfix would affect the login process,  and I don't see how the Word or Powerpoint hotfixes would.  

The only other one that I'm not so sure about is the Internet Explorer cumulative update, MS06-021. That's the one that  usually has the obscure fixes that break things behind the scenes.  The  block on the ActiveX "fix" that broke a lot of things is gone and that ActiveX "fix" is now permanent.  Maybe it's an ActiveX thing, who knows?  The "Internet Explorer" hotfixes also mess with the basic file management and code execution API set of Windoze, a direct result of them having kludged IE into the Windoze kernel to "prove" it's part of the OS, to get away with their illegal bundling scheme...  and we're still paying for it today.

I wish they'd give more than just the files that get replaced 'cause you know dang well they futz with the registry and stuff.   They probably delete things too, but don't tell you what.

A little more Information After a lot of searching it was not a Patch problem although I am running WSUS connected to about 1/2 of my clinets all of the clients had the problem.  

Turning off NMAS worked, and that is what I am currently dooing to keep users connected,  The underling problem is still in effect.  NMAS was to be used to allow for Biometric readers and smart cards for Novell Netware logins.  Till I can figure out what the NMAS error is all about that project will have to be on hold.

There are no server errors or abends.  However I can not get iManager to run on that server.  I have to use it off of another server.

Thanks for every ones help.  All of the ideas were good ones.  I have a call into Novell about the problem (still waiting for a call back 16 hours and counting).  I will post any follow up that comes along.

yes and just for grins tried an older one as well No Luck

All works fine if i disable NMAS

Does NMAS secure via certificate?

Could this be some form of certificate experation?

It depends on the method, I'd wager.  What methods do you have enabled?  You say there's a problem on a server with iManager - is that a load issue (tomcat and/or apache) or is it that you can't access it from your browser?  Does that look like a cert issue?  If so, then they may be related.
