Servers Lose Connection to Domain Controller

-

i have strange issue don't know resolve. here's have:

configration:

all server windows server 2008 r2

i have domain setup has host hyper-v servers (10 of them). domain controller domain dns server.

on host hyper-v servers have multiple virtual servers. of them stand alone (workgroup) , several of them in domain. 

all these server use dns server host domain (i not have dns installed on of virtual domain servers).

all servers in workgroup have rds , rds licensing on them.

one server in each of virtual domains has rds , rds licensing while others servers have rds.

problem:

this has happened 3 times in past 4 months , issue resolves after hour or two.

on 3 of servers in domain, rdp access them lost. tries connect after period of time times out or , 'access denied' button. after while 'applying computer settings' several minutes , logon. however, i'm unable connect other server in domain , pop warning stating no remote desktop license servers can found. i've tried rebooting no avail. 1 of the servers removed domain i'm unable join domain because domain controller cannot reached (even though can ping ip , name).

after hour or so, things start working without explanation. errors in event log basic 'cannot connect domain controller' , check dns what's odd has happened @ same time of day on each occasion. , 1 server started working after 50 minutes while other 2 took on 2 hours resolve.

i not see issue of other 18 servers. none of stand-alone servers (workgroup) , of servers in domain). in fact, there servers in domains have problem can access no problems. it's couple servers do. 

any suggestions appreciate. i've looked @ dns, duplicate ips, made sure licensing service running , cannot figure out.

thanks!

looks ok. i'm wondering network issues, routing loop, etc. might want ask vswitch configuration on here.
