This has been baffling me for a week now. Here’s the scenario:Office peer-to-peer LAN of 8 computers, all connecting to DSL via Sygate3.1 through a “host”. All use 10/100 PCI NICs to network.
Host: TCP/IP 192.168.1.7 / subnet 255.255.255.0, DNS & gateway unassigned.
Using Speedstream 4160 USB DSL modem
Clients: TCP/IPs 192.168.1.X , X= 1 through 8 (excluding 7). Subnet mask 255.255.255.0 Set in I.E. to access browser via LAN. Gateways are set to 192.168.1.7, DNS set to 192.168.1.7
All works fine, everybody can browse, Quake, etc.
THEN … I build a ninth computer to act as a “server”, hosting the DSL, the printer and all the commonly used data files. To make settings easier, I shut down the old host after removing it’s NIC’s TCP/IP properties and Sygate 3.1.
I set the “server” up as the new host, loading Sygate 3.1 and setting it’s TCP/IP properties to 192.168.1.7
The “old host” gets a new IP (192.168.1.10), 255.255.255.0 and DNS and gateway of 192.168.1.7. It’s set to access I.E. via a LAN.
Everybody boots up, the LAN has everybody showing up. The server/host is on the ‘net AND the “old host” connects and browses just fine ….. BUT:
…The other 7 computers CANNOT browse , HOWEVER they CAN:
1. Get msn.com when I.E. is opened up. This is I.E.s default webpage. Netscape gets nothing but a time-out.
2. Get to URLs on msn.com’s home page but I can’t get to any address via inserting the www address in the destination bar
3. Ping any vvv.xxx.yyy.zzz. address successfully, like put in F3D’s or Yahoo’s address and get packets back, but I CAN’T get there via the browser.
4. Load up Q3A and get servers and play.
I checked the settings in 192.168.1.10’s devices and TCP/IP protocol against the others and they are identical, save the Ips last digit and the “host name” in DNS config, per Sygate’s instructions.
Make one simple change on a working system and everything goes to hell … but NOT consistently as ONE client works just fine.
I would guess this is a browser issue, perhaps even involving the ports …. But I don’t know. EVERYBODY on the other 7 computers is getting a little pissed at me (I’m included) cuz not only can they not browse, but they can’t get their company e-mail.
Anybody got a clue of where it’s messed up ???
