Unable to ping new server

Unable to ping new server

I have recently rebuilt a Compaq DL380 P2 to run Server 2003. All rebuilt ok, I can ping anything from the server, however, NOTHING can ping the new server. I dont think it a firewall issue, mainly because When I try to access the firewall I get the following -
Windows firewall cannot run because another program or service is running that might use the network address translation component (Ipnat.sys).
Any advice would be very helpful.

Hi Ian.

The first thing to always check is your subnet mask and default gateway of that server. I am assuming that is correct.

Trying to find a process in Windows thats binding to a IP address and port is a lot more difficult but netstat -an may give you some clues.

Ok, I did that, the output is attached.
Is there anything on that which might point to an answer?

Hello Ian.

I think your suspicions may be confirmed. If you look on your system you will see its listing on ports 1025 and 1028, which are common ports for a variety of backdoor trojans.

All the rest seem to have feasible users or seem legitimate.

Re: Unable to ping new server

It is a purely internal server, so

In routing and remote access
nat/basic firewall
lan
change to private interface


The problem went away
