Win Server 2003

I have a server that runs Windows 2003 standard. I built a Windows 7 desktop and created a shared drive on the Win 7 Pro box. These are both in the same domain and on the same subnet. The Windows 2003 server was not having any issues at first with accessing the Windows 7 shares but now it has lost the ability to access the shares on the Windows 7 box. What is really weird is that the Windows 2003 server can still access shares on any other boxes or servers. I have made sure the firewalls are off and disabled any antivirus apps.
This is the error I receive on the Windows 2003 box when trying to connect. Image attached.

Can you run ipconfig on the win 7 machine and see what IP address you get then ping the win7 machine from the win2k3 server and see if both are the same.

If the addresses are the same then try doing a runas as a user that has permission on the win7 box e.g

runas /user:win7pro\user1 explorer
then enter the password it might just be as simple as the shares on the win7 box have not granted permissions to the account you are using on the win2003 server

Also are the users members of a domain or are they just local users on each computer in question?

After determining they are on the same network segment and nothing network-related is preventing the communication as recommended ...

Are you connecting with local or domain credentials?

Does Windows 7 have its domain network connection labeled as Home, Work, or Public?

How many computers are using this share?  Mapped or direct?
TabDBAuthor Commented:
They are actually plugged into the same switch on same network. Tried local and domain credentials same issue. It is set the same for Work and Domain Current Profile. I have at least three servers that can connect to this share. I only have this one server that cannot connect.

I have now been told by several others that Windows 7 has an issue with Windows 2003 servers connecting to shares on them. 2008 and 2012 servers seem to work fine with connecting to a Windows 7 box. Any thoughts?
PowerEdgeTechIT ConsultantCommented:
Just curious ... why are your shares on the workstations instead of the servers again?
TabDBAuthor Commented:
I ordered this very large capacity Windows 7 Pro workstation to send backups to. So all my servers send backups using LiveState into the shared drive of the Windows 7 machine.

I see ... I'd have to think there is some difference in authentication from XP to 7, although I'm not sure where I'd look.  (I only ask, because I have 2003 servers with shares used by Windows 7 PC's with NO problems ... so I can only guess that some level/protocol (NTLM possibly?  2003 would likely be using v1 (default) and 7 would be using v2) of authentication is the difference.)

Closing this issue. Have redirected the backup of this server to another server.
