virtual centre failure to authenticate with the server?

[Mayank052011101]

Hi,

While we are trying to log in to our VC, it takes unusually long and then pops up the wondow stating

virtual centre failure to authenticate with the server.

While browsing the VC log files, we got these enteries...

'App'  opID=686F96AC-00000003] vim.fault.SSPIChallenge

I searched about it, it says this "vim.fault.SSPIChallenge" occures when some further negotiation is required during authentication...http://communities.vmware.com/message/1442291

Can anyone please help on this?

Thanks in advance for any suggestions on this.
