server 2003 can not see entire network

I rebuilt an old server, gave it an IP, set up the net card for dns servers and added it to the domain, server 2003 and added SP2. The server can not see the network. can not browse. what am I missing?  I have DFS and I run a startup scrip that maps network drives and all the DFS drives do not map but 2 of the domain member servers do.

are these servers all in the same subnet? I'm not a network engineer, but I think that could explain the behavior you're describing.

for example, I think a server at would be unable to communicate with servers in the  10.200.2.x subnet unless you change the subnet mask to

subnet mask is ip range is 10.10.10.?, fire wall is off, no A/V installed yet. This is the wierd thing the DNS shows the computer listed correctly but ping yieds only 2 answers in 14 tries, Intermittent!

Most likely.
Bad Cable, Bad Switch (Common in consumer line switches), or Bad NIC.... in that order.

Is the switch a 10/100 or 10/100/1000? If it does 1000 (Gb) you need at least CAT 5e cable and patch cords or you will have intermittant connectivity.

To bypass a wrong cable issue, you can force the NIC to 100 on the server and workstations.

I will check that tuesday. Thanks. It is a 10/100/1000 nic card and is plugged into a 10/100 switch. I assumed it would be automatic like most other machines I have.
It is automatic, if you ping the router from a workstation, do you lose pings?
jrdregsAuthor Commented:
If I ping from a workstation no issues but this serve r looses pings very intermittent.
I would replace the patch cord and then the NIC.
