Question : Windows 2003 server will not allow me to access shares since upgrade

Recently did a bunch of Microsof Windows updates on a Windows 2003 domain controller.  Been having major issues with the shares and domain policy since.

I cannot access the shares from the server itself but can access them from any other PC in the office.  I can go to \\ServerName and see the shares but when I try to access them I get and message "No network provider accepted the given network path."

Also I cannot got to \\IPAddress I get the error "Windows cannot find IP Address"

Third symptom is when I try to open Domain Security Policy it says it cannot find any domain controller.

I have dont sfc \scannow and have tried uninstalling and reinstalling File and Print shareing.  "Client for Microsoft Networks" is installed.  And I am not getting any additional errors in event viewer.
 HELP this is bizzar.

Answer : Windows 2003 server will not allow me to access shares since upgrade

Are you using SEP? If you are please download the cleanwipe tool to fully remove the product.

I use McAfee now since Windows 2008 server came out because of all the issues Symantec and other products caused huge problems.
