User is being told Server not accessible.   You might not have permission to use this network resource

I have a network user who until 2 days ago was able to access their folders on the DC/file server.   All of a sudden they are getting an error message stating they cannot access the server.   The user is part of a group on the server and this group has full access to the folder they are trying to access.   The network is running fine since I can access the server from this computer via "administrator" sign-in".   The user is able to sign onto the network but all other access to this server is not possible.  The server is Server 2003 and the computer is Win 7.

Log into the problem computer as the problem user. Run cmd.exe.

NET USE Z: /Delete and enter for ALL mapped drives. Restart and try again to connect.

Check the Share permissions on the folder itself. I had a similar issue once, and it turned out that although I had given access to a folder, the permissions differed for some reason. Go to Advanced Sharing on that folder in order to check the share permissions for that group/user. You may have that user in there in addition to the group with a different share permission set, which would take precedence.

John, I tried the "Net Use Z:/Delete" and it says the network name cannot be found.

Do the same thing and type just NET USE  .  What comes up?  Any list?

Try the NET USE Z: command again and please give use the error number. There is more than one that comes up.

I ran Net Use and it says there are no entries.  

I ran Net Use Z:  and got "The network connection could no be found.   More help is available by typing NET HELPMSG 2250."

The message is not illuminating at all. The user appears not to be connected at all.

Can the problem user PING the server?  Try that. What happens?

Check the firewall settings. It could be blocking the connection.

Check the problem machine for viruses and malware. Look in the HOSTS file for invalid entries.

Every time I try to map the drive, the error says there is "An extended error".   Not sure what that means

Can you PING?  and what about the Firewall?  There is a basic connection issue. Check the network connection, sockets and cable. Try a different drop.

I ran Microsoft essentials, but it found nothing.  I pinged the server via name and IP address and it both were 100% successful.

Would deleting then recreating the user help?

Try a different user. Make a test user before deleting the current user. Try the different user and see if you can PING / NET USE connect.  Record any errors. The current profile could be damaged.

I think what you have is User Account damage. The admin works, so the network is OK, the NIC is OK, the Firewall is OK.

Make a new profile for the user.

Users users, users. Sigh!

Damaged user account.

When you replace the account, you want to scan completely for viruses and malware.

By deleting and replacing account it worked.   I will check for viruses/malware also.   Thanks
