I'm managing about 20 computer for a small business, and set up their network yesterday. We have a server that fills multiple roles, including DHCP, Domain Admin, and file sharing/storage.
Today all of the computers have access to the internet and the server files with the exception of one. This happens to be a laptop and not a workstation, but it's still using hard wired internet(although I've also tested with wireless). The issue we're having is that this one computer cannot log in to the domain. At bootup, he logs in to the laptop with his credentials and logs in to the domain(called Radar). No problems here.
This is an engineering company that uses WinXP so the laptop is old and slow. It usually tries to sync files on the domain but the progress bar never moves. Sometimes a domain login window pops up, and if I enter his credentials and hit enter, nothing happens. The login window acts like nothing happened; it's movable, credentials can be changed, and it can be closed with no problem. It just never actually connects.
Now if I close the sync window and try to access the domain server files I get similar, but sometimes stranger issues. Sometimes it says that the domain is unavailable. Sometimes it says he does not have access to the files. Sometimes a window will pop up saying a possible security threat was detected. If we do get a login window to pop up, it's the same deal as before. He is one of 2 users with Administrator privileges, the other of which has no problem logging in and accessing the server.
He does get internet access with no issues, and I've checked the ipconfig to make sure it's an IP assigned by the DHCP with the correct gateway. No problems there, he just can't access the files. I'm not much of an IT person, so can anyone help me troubleshoot this?
Edit> I forgot another very common behavior, where clicking on a drive on the file server will show him the file tree but if you look through the folders all of them are empty. Could this be an issue with the drive mapping?
Edit 2> Here is a log I pulled from his machine after a login attempt:
Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5719
Date: 8/2/2012
Time: 11:02:40 AM
User: N/A
Computer: C046
Description: No Domain Controller is available for domain RADAR due to the following:
There are currently no logon servers available to service the logon request. .
Make sure that the computer is connected to the network and try again. If the problem >persists, please contact your domain administrator.
Data:
0000: 5e 00 00 c0 ^..À
There was also an error log about not being able to find a domain controller to set the time, so it's not making a connection with the DC. There are no relevant logs on the server side of things.
"including DHCP, **Domain Admin**, and file sharing/storage."Do you mean Domain Controller? – MDMarra Aug 2 '12 at 15:38"he just can't access the files."mean? Do you get an error? What does it say? What's the event log say? Who is the logged in user and what are that use's effective permissions on the share's NTFS ACLs? – MDMarra Aug 2 '12 at 15:40
