Local server logon causes freeze/server lockup

Recently I have noticed that with this particular server, if you logon locally or through rdp, the server seems to freeze and lockup. It also stops responding to clients, as an exaple the server is running exchange and the outlook clients loose their connection. After a minute or so it seems to come back. Just wondering if anyone might have an idea as to what might cause such an issue?

Many things can cause this problem:

Sysexpert is right in trying to pinpoint the problem by looking at the event logs, and services.

It would also help to check a DCdiag report, netdiag report, and IPconfiguration.

With limmited information, my first guess would be a dual NIC conflict. But, there is no way of telling with limmited information.

Logged in today and the issue occured as it normall does, the only error in the three normal logs was a NSSDK.SnmpValidatorLg error, event ID 8226. Nothing in the DNS, FRS or directory service logs.

Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

NSSDK

SMTP= Simple Network Management Protocol
validator
Lgcy1=Legacy1

Do you have a sharp printer/fax on the network or attached to the DC?

The problem appears to be with a Sharp device the disables network connectivity. Until I research this more, maybe upgrading the NSSDK software from the website to the latest version will fix the problem.

I found a bunch of people with the same issue. But, none have provided a fix. The NSSDK software belongs to sharp. It is a third party application. SNMP is simple network management protocol and the validator has soemething to do with permissions.

This link says there may be something wrong with the fax line.

Honestly I don't know the fix. Are you running legacy computers with NT, 98 or 95 on your network?

For a solid conclusion, I think I would contact Sharp's customer service. These issues must have been brought to their attention before.

Was contacted by sharp. There was an app installed on the server "Sharpdesk" which they said shouldn't be on there, it's a desktop app, also to go into the printer properties, under port config, make sure the snmp box was unchecked and to also remove any ports not been used.

Have removed the app, the snmp option was only available on one printer so have unchecked it anyway, nothing at this site is using snmp so that should make a diff. If this works im not sure how it might help ppl who are using snmp to monitor their devices?

Will see how this goes.

Maybe the update on Sharp's third party software was the answer. I am sure there was a lot of requests for a patch from Sharp to overcome the problem, maybe Sharp resolved the problem. Let folks know how Sharp handles the sitiation:: That's the best you can do if you wish to help others.

well ever since i  

"Have removed the app, the snmp option was only available on one printer so have unchecked it anyway, nothing at this site is using snmp so that should make a diff."

We haven't had any lock ups on logon so it appears as though it's fixed for now. Unfortunatly I cant really shed anymore light than in previouse post but i hope it helps someone sometime.

We had the same problem with a workstation where RDP access results in a black screen and only rebooting the computer makes it accessible again.  Same scanning software, same error messages etc.  However, Sharp tech support won't help because it's a commercial scanner and they pointed us to dealers for assistance.  The workstation in question has Windows XP SP3 running on it.  Other conputers in the same environment have SP2 and do not have the same problem.
How did you get Sharp tech support to help?  I can't imagine dealers will be of assistance with this.
