(I'm writing this from an old backup PC. My primary PC, a K6 running Windows 95B, has the problem.) Last week I re-ran Windows 95 setup from the CD-ROM, asking it to replace any corrupted system files. (Had been getting blue-screen messages about an invalid Windows configuration, telling me to run setup again.) Whenever setup found a newer file version than the one on the CD, I told it to keep the newer version. After this operation, my modem dialup connection to my ISP didn't work any more--it said no PPP was present. I had to reinstall the TCP/IP protocol package from the CD (it had disappeared), and then bind the Dial-Up Adapter toTCP/IP. Now I can connect to the ISP through the modem; the connection logs all the way in (Password verified, etc.). But when I start my mail application and it tries to reach the mail server, a dialog pops up: "Error getting network address for mail..net. Cause: requested entry not found (11004)." Internet Explorer is also unable to find the address of any web site. I have reinstalled the ISP's software package several times. No effect. I have reinstalled TCP/IP from the Win95 CD several times. No effect. Under Start->Settings->Control Panel->Network, here is what I see: Configuration tab pane: Client for Microsoft Networks Dial-Up Adapter SMC EZ Card ISA 10 Adapter NetBEUI->SMC EZ Card ISA 10 Adapter TCP/IP->Dial-Up Adapter File and Printer Sharing for Microsoft Networks TCP/IP Properties under the Dial-Up Adapter shows: IP Address Pane: Obtain Automatically WINS Configuration: Use DHCP Gateway Pane: None DNS Configuration Pane: Disable DNS NetBIOS Pane: Support is NOT checked Advanced Pane: "None" Bindings Pane: Nothing checked Under My Computer->Dial-Up Networking->ISPname->Properties->Server Types, I see: Type of Dial-Up Server: PPP; Windows95, WindowsNT3.5, Internet Advanced Options: Enable software compression Allowed Network Protocols: TCP/IP Under the TCP/IP Settings button: Server assigned IP address: On Specify name server addresses: On, with values: 208.198.56.2 208.198.56.3 0.0.0.0 0.0.0.0 (These hardwired DNS addresses were installed by the ISP package; this old computer, with the same addresses, works fine.) Use IP Header compression: Checked Used default gateway on remote network: Checked I'm stumped. It seems TCP is installed and configured, but applications can't get to it. If I run "winipcfg" from the Run dialog while logged into the ISP, a dialog says: "Fatal Error. Cannot read IP configuration." Thanks, Joe Nelan

wow.....wild and wacky. Have you tried running "ipconfig" from a command prompt? That's crazy, not being able to read the IP configuration. Have you tried removing and reintalling the modem using updated drivers? Or perhaps a known-good modem? If the computer doesn't know its own IP address, that would explain why you can't access anything....it's unable to give remote machines a return destination. Have you tried pinging the loopback address, 127.0.0.1? Or perhaps assigning a static IP address while offline, then ping yourself? How about pinging remote machines? Of course, it sounds like you've able to make contact, but after you connect, it isn't performing. Finally, are you able to browse your own machine using IE?

Curiously, ipconfig.exe isn't found on either of my computers. The ping 127.0.0.1 returns: PING: transmit failed, error code 10091 Setting a hardwired ip address for the system and pinging it (after a reboot) gets the same error. Will try the modem reinstall. But it seems the modem is functioning fine. For instance, I can get to other dial-up destinations like my bank.
