Domain controller - can´t access shared files

[siki85]

Hi guys,

I need help...suddenly all users can´t access to resources located in shared files on different servers. A message appears telling that there is no access....

Our domain controller (DNS services, DHCP services, AD services) doesn´t show anything strange...

The only message I got is a warning with the message " the server service was unable to map error code 998".

I already checked for viruses, nothing...

Any advice please...

What does a local ipconfig /all say? Can you ping the servers? Have the Users lost connectivity? Assuming the Shared Files are in a Mapped Drive? Any power outages recently or changes to internal network equipment? Restarted the DHCP/DNS services?

Do this (adding to first reply):
Ping server by name from CMD prompt from workstation. Does it respond?

Ping server by IP address from CMD prompt from workstation. Does it respond?

If either fail, you have to start troubleshooting there.
Post IPCONFIG /ALL of a typical workstation and the server - label which is which.

Anything here?
