Windows 7 will not reolve to or ping and internal network address

Windows 7 will no longer resolve to an internal URL in our facility.  The Windows XP machines still do.  We have tried everything.  No interal changes have been made to the network.  It just stopped working one day.

As it urns out,  there was another device on the network that was running arp proxy.  Once turned off, everything worked fine.

Did you try using nslookup?

Does the URL have a full name (FQDN) such as myserver.mydomain.com or just myserver?

Is IPv6 disabled on the Win7 machines? Try turning it on, if so.

Ipv6 makes no difference on or off.  Full domain. nslookup does work.

Have you changed dns suffix lists recently? Have you tried to disable the firewall, then wait a few minutes and try again?

Heiden_ConsultingAuthor Commented:
Have done it all.  Looking to DNS records Firewall configs and malware that may have run into errant traffic and disengaed access for security reasons.  Done it all and nothing.  Xp resolves for a time and then quits.  We reset the arp cache on the server and connectivity resumes for Xp.  The other card obn the server is fine and PCs always within this self contained network.

"The other card"? Do you have multiple NICs on the server I.E. it is multihomed? If this is the case, you must unbind Netbios from all server NICs but one facing the domain and disable all dynamic updates to DNS.

ToxaconCommented:
"Dynamic updates to DNS" means that the NIC does not update DNS but you have to update it manually.

static IPs all the way around

Does each adapter in the server have a default gateway?

Yes, you can have static IPs, but is the option "Register this connection's addresses in DNS" selected in all adapters?

One adpater has a gateway.  The problem adapter.  One adapter points to a closed network that does not acess the internet.  This one is fine.

Each adpater had the "Register" bosx checked.
