I am having a simular problem. I was able to openshared folders and printers and now after the latest Microsoft Updates I am not able to any longer. I can only see myself in the "Network" utility. I am able to manage all my routers and NAS drives using iexplorer. I am able to print to IP printers. I can not map or print to UNC paths. This is a wide spread problem and it needs to solved. I is all over the internet. If anyone would like to remote in please feel free. Brent

Hi Brent, do you mean those Windows XP computers cannot be displayed in Windows Vista Network? If this is the case, I suggest you first check the solution in the following KB article: Network Map in Windows Vista does not display computers that are running Windows XP http://support.microsoft.com/kb/922120 Hope this helps!
