I am running Windows XP Pro on a laptop.  When disconnected, all programs open quickly.  When connected to a network, however, a simple text file takes upwards of 60 seconds to load!!!!   Even right-clicking a file to display the properties windows experiences the same delay. I have no mapped network drives, but I do have network printers.  Curiously, opening or right-clicking a file seems to generate significant network traffic, but I've scanned my computer for viruses/spyware and came up clean.  I've exhausted my theories and will now exhaust my 125 points in this forum -- HELP!!!!

Problem solved!!!  A program which I previously installed using a UNC path was the culprit.  The server where the program was installed from was taken off the network and nobody told me.  Even though I wasn't using this program any longer, Windows XP was sending out packets to this non-existent server each time I double-clicked or right-clicked a local file.  I was able to find this by using a wonderful network packet sniffing program called SnoopAnalyzer Standard Edition (freeware).  Each time I right-clicked on a local file, a score of TCP packets were blasted out via the NetBios protocol.  After about 60 seconds, the properties window finally displayed as expected.  I searched the registry for any references to this server, uninstalled the culprit program and manually removed any remaining registry entries referencing this server.  A quick restart and I'm back in business.  I hope someone else can benefit from this solution, because we all know how diligent our network staff can be when it comes to considering the dependencies of their actions.  Happy (and safe) computing!
