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.
