Join Windows 2003 Member Server to Domain: Network Path Cannot be found.

hey –

i’m having problem adding servers domain (network path not found). here’s story.

a group @ company came me , wanted me migrate virtual hosts 1 vcenter another. additionally, p2v remaining physical hosts. 2 of servers – upon login domain account refuse logon error (after accepting credentials) “rpc server unavailable”. okay fine, still logon local admin accounts, figured i’d deal after got done p2v migrations. went off without hitch, still receiving “rpc” error message stated previously. installed sp2 on servers had not been done yet bring them @ least sp level patching. no change. started digging around in dns , found there used additional dc decommissioned , not demoted/removed. frustrated, went through dc metadata cleanup , removed entries dns – thankfully, there no roles seize, cleanup went without hitch. thinking cure problem, tried add server domain again, no change. fired wireshark on dc/dns server , noticed every machine on domain sending dns queries trafficconverter.biz – yup, conficker. spent majority of last night cleaning pcs on domain. strangely, 1 of first servers having trouble – after cleaning conficker, av update , scan (the av dats hadn’t been updated in 3 + years) , reboot, happily joined domain. thought onto something. first machine worked, second didn’t. third , fourth failed same error “network path not found”. @ point, i’m having more trouble when started – straw broke camel’s type situation. so, went machine joined earlier, unjoined, re-booted.. fail.. and i'm square one.

at point, know:

• i haven’t ruled out dns, i’ve exhausted every test come across , come fine.
• dcdiag/c  comes clean dc
• the servers can resolve _ldap._tcp.dc._msdcs.<domain name> srv record via nslookup
• the windows xp clients seem remain unaffected phenomenon – although, heavily infected.
• if run wireshark during domain add, client starts communication, receives answers server, sends requests server never receive reply (see attached)
• i think problem, don’t know enough what’s going on during process pin point problem.
• during successful re-add (when server magically joined) there gamut of traffic between dc -> server after point stops.(see same attachment)
• all servers windows 2003 ee , @ patch level of sp2
• all server have been scanned conficker buster kaspersky , full scan of mcafee 8.8 dat update yesterday

i'm @ wits end this. hoping there's out there that's more knowledgable domain join process am, , might able tell me based on information provided.
