Explicit EAP failure received

solution of nps works on ten desktops. able succesfully authenticate using dot1.x , proper vlan. new desktop batch of 3 machine, newly installed 2 days unable go through dot1.x authentication.

instead ends @ explicit eap failure red question mark on network adapter. client windows 7 ultimate.

any ideas can difference factor between these windows 7 machines, causing few pass , these new ones fail.

services of napagent , dot3svc started, same nap settings through gp on machines.

also executed sc config dot3svc depends = napagent.

switch 3com model 4210 working other windows 7 desktops.

any idea ?
