UPdate:  I can get into all the other computers with remote desktop.  Just not server 2003. Also all the map drives work.   Just cannot make a new one.

Thanks

RDP and Map Drives are different and you say both do not work properly.

Try TCP/IP Reset and DNS Flush. Easy as a first step.

Delete all wireless profiles
Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Restart the computer
Remake wireless profiles as needed

Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache

Since all worked just prior, this may work.

Next, try System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete, shut down the computer. Start up and test.

Let us know if either of the two suggestions worked.

Is it just the one server running 2003?
Have any policies been changed?
Check the remote connection manager on the 2003 server see if any settings have changed to allow only connections froma secure location has been enabled or something liek that.
If it's coming up with and encryption problem and you have not set any encryption you might be infected with an crypto locker of some sort on the server.

I can connect to the other machines fine.  Also the phone system connects to window server.

Checked out the server 2003 and all seems normal.  What do you want me to check.  I know it got a lot of updates the other day.

Try the 2 suggestions in my post and let us know back.

Also, if the 2 suggestions don't work, think Malware and scan accordingly.

can you try RDP to it from any other clients on your network?
i'm not sure deleting wireless networks on a wired desktop client is going to do much good.. saying that there is no mention that you are on a wireless client am i missing something?
also if you are accessing the RDP session via IP address flushing the DNS wont help resolve your RDP issue

All the map drives work on all the computers to the server 2003.  We tried two clients and both received the same error as I received.  All of us can RDP to the phone system server with no problem.
That is another windows 7 computer.  Its just that server.  I  noticed in the last 3 days, it wanted me to send an error report, and I had to choose why it shut down.  There were several error messages, too many of them to be true.

I can go over to the server and manually do anything it want to it.  We did have a lot of updates though.  We are looking into sinology nas system for a replacement for this thing.  But I have to keep it running for a couple of months if its possible.

Thanks
