Microsoft Server 2003 ... clients cannot PING by IP or name ... but server is working 100% (probably a simple fix) (see Q: for loads of details) ...
Posted on 2008-06-20
Windows 2003 server
IP address 192.168.1.3/24
NetBIOS name: appraisal2
Server is Domain Controller, DNS, and DHCP (all 3 services started and running) ....
The server had a 'power outage' and had to be started up from an powered OFF state this morning.
The Internet access is here is cable, and the Netgear 'router' is at IP 192.168.1.1.
Right now, the server can ping all clients on the LAN by name and IP (about 7 or 8 PCs and a few printers). The server can can ping out to the Internet by name and/or IP address. Things seem to be working fine from the server side.
The client machines boot up, get their IP from the above server, and then can log into the domain (again via the server above). The clients cannot get out to the Internet (neither by name or IP address). The can ping each other, but no client can PING 192.168.1.3. If they try, it will time out. This is strange in itself because this has always worked (prior to the power outage). There is 'nothing' running on the server to prevent this (because it was working prior to the power outage.
If I 'change' the DNS setting from obtain automatically, and hard code it in as 192.168.1.1 (which is the Netgear router), the clients can then at least get out to the Internet (by name or number) ... but they cannot reach 192.168.1.3 by name or IP address.
This seems really simple and basic on face value.
I've tried stopping and restarting all services (DNS, DHCP, etc.). I've checked the event viewer, and there is nothing outstanding in any of the log files. Things look 'clean' on the face.
I tried to 'rebuild' TCP/IP with the netsh int reset command, but that was not the fix. I've restared (and cut off power) a few times to the server.
I've turned off all printers and computers, and then I restarted them AFTER the server was up and running.
I'm not sure what to try next.
Clients can ping each other, they can ping the Netgear gateway, but they simply cannot reach the server at 192.168.1.3 (by name or IP). I've tried changing the IP address on the server to 192.168.1.33, and the results were the same.
I've cut off the power to the switch involved, the Netgear router, the Internet ISP 'router box' ... and all computers and printers.
To me, it seems like something might have been 'broken' with the DNS software on the server.
Re-CAP: All was working fine ... the workers came in to a power outage on the server ... once the server was restarted, this state of affairs was the result.
Any tips, suggestions, or advice would be greatly appreciated.
