Holy Toledo!! Thank you cluberti! I don' know why the hec I didn' think of that! The TCPIP configuration on the 2nd workstation (that does not exhibit the problem) is all dynamic. This WS is a laptop that the user travels w/ frequently. I couldn't assign a static IP for the laptop w/o the user always having to change it. The router doesn't have MAC address reservation capability but I needed a consistent IP for port forwarding to both computers. So, I'd assigned a static LAN IP to the desktop and allowed 1 DHCP address on the router. This gave me the predictable IP for the laptop that I needed for port forwarding. The laptop, w/ it's dynamic TCPIP configuration, showed the ISP's 3 DNS servers in ipconfig /all. The desktop PC's TCPIP config DNS had been set w/ the LAN IP for the router. I checked the router for the ISP's current DNS servers. Entered them into the TCPIP config for the desktop PC. Voila! Worky worky. Thank you very much. I am still going to check out those utilities for my own edification, btw, but need to quickly get everything re-enabled in time b4 the user comes back from his lunch mtg. --------------------------------------------------- A fortunate "side effect" of making the DNS change (could be coincidence but I know it didn't work this morning when I tried it): I have ATI (Acronis True Image) scheduled tasks set up to email a report to me after every scheduled ATI task has ran on the desktop PC. Previously, I was unable to get the email configuration to work in ATI through the ISP's SMTP server. I ended up using an alternate SMTP port on my own domain. While it would pass the "test" w/in ATI's notification options, I'd never get the email. Now, still using my alternate SMTP port, it passes the email notification test AND I get the email. Who'd've thunk it! Tonight I'll try setting it up w/ the provider's SMTP server and see if that works. --------------------------------------------------- I'm a happy camper. Thank you again.
