Web client issue. I can logon by "Use Windows session auth" but it denies when i put manually

[adrianrus00]

vCenter 5.5

Out of a sudden, this weird thing happens:

when i open the web client and i try to TYPE MANUALLY my credentials, it denies my acces

but, if i CHECK the "Use Windows session auth" box and press Login - it works.

Do any of you have any idea why? Thanks

problem solved:

when i tried to login the VC itself, it gave me credentials error. I understood that AGAIN there is a problem between the VMWare and Windows 2012..

my VC is on a Win 2012, or the ethernet controllers were still not solved byt ESX 5.5 version and so on....

after reboot, all came back to normal.
