My client has a W7 Pro (64-bit) client that is unable to browse the network from Windows Explorer. When one clicks the > arrow next to 'Network' and wait, nothing happens. There is an error message, but I forgot to write it down. The message, however, included the words, "Access Denied". This PC is part of a domain with a single domain controller. Interestingly, other networking services work. For example, from the command prompt when I type 'NET VIEW', it correctly lists computers. And if I type 'NET VIEW <SERVER>', the list of shares on the server appear. Also, I am able to map a lettered drive to a known share on the server from within Windows Explorer. When I checked the event viewer, there was one error message that might possibly be related: Log Name: System Source: Microsoft-Windows-GroupPolicy Date: 3/16/2012 1:34:34 PM Event ID: 1129 Task Category: None Level: Error Keywords: User: <domain name><username> Computer: Workstation02.<domain>.com Description: The processing of Group Policy failed because of lack of network connectivity to a domain controller. This may be a transient condition. A success message would be generated once the machine gets connected to the domain controller and Group Policy has succesfully processed. If you do not see a success message for several hours, then contact your administrator.

Dear Sabrina, There has been no progress on this task because I have not been able to reach the end user's computer. At this point, I am treating it as a possible malware problem. Also, the mapping of letter drives to specific shares seems to be a satisfactory work-around for the end user. Perhaps that is why he is procrastinating. If and when I have progress to report, I promise to repost here.Herb Kolodny
