Well, I'm not sure if I solved the issue but I have managed to get the network browsing working. After verifying that I didn't have a master browser conflict by using the nbtstat information I then reviewed the ipconfig /all details and noticed that I had no entries in the WINS primary or secondary fields so I manually entered each's machines IP address's in the tcp/ip advanced settings for the WINS tab. After stopping and restarting the WIN service I could then browse to each and every machine by using the network neighborhood, from every machine. The access time seemed to be a little slower, at times almost feeling as though operations were going to time out but they did populate on the screen and worked properly for file transfer, .... Hop this helps someone else as the corrective information on this type of issue is very scarce. Rgds
