unable to access the sysvol folder

Hi All,

We are facing issue with the sysvol folder in windows 2003 server Active directory.

“C:\Windows\sysvol\sysvol refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location.”

any one can help me.
