1. I removed the NetBEUI protocol on all machines... same results.
2. It is difficult for me to change the settings of my work PC. What I did not make clear is that I have a home office. I use a Cisco VPN to connect to our main servers for MS Exchange, internal shared disks, and Intranet.
3. You are correct. I also had TCP/IP on my home network.
4. Whoa! I just figured out something. I can't believe that I never saw this before, but it appears not to be intermittent, but based on whether I am connected to the VPN.
Here's what I have experienced a couple times in my testing:
- If I try to reach the home network while NOT connected to the VPN, I can NOT connect.
- If I am connected to the VPN, and I try to connect to my home network, IT WORKS!
- After a successful connection to the VPN, even if I am disconnected, I can still get to the home network disks. (The Cisco VPN still needs to be active however. If I close the Cisco VPN software, I can not reach the disks.)
Bryses: your questions made me investigate this further. Thanks. At least I have a "recipe" that works.
If this tells you what is causing this, then great. It would be nice to have it work all the time, but I can live with this approach.
Thanks,
Rob
