i feel ghost haunt me legacy server died, not sure tests conclusive problem begin start resolving these issues

any direction of great help

cheers

 

two things note possible issue.

1) dns server should pointing itself.  should not point external dns servers in tcp/ip config.:194.72.0.114 &   62.6.40.178

2) appears domain domainname.local.  server's primary dns suffix 'myserver.local'?  server's primary dns suffix should same ad domain name. 

the best thing while there "slowness" on network take a packet capture , see happening on wire @ time.
