The viewstate is invalid for this page and might be corrupted

[WFB]

Hi,

I keep randomly getting this error: "The viewstate is invalid for this page
and might be corrupted". Ive searched the newsgroups and the web and havent
found anything that has fixed this. Is anyone else getting this error, and
is there a fix somewhere that Im missing?

More details:
Error only occurs in loadbalanced environment
Error can not be recreated on demand and seems entirely random.
Error is happening in more than one application

Thank you very much for any help anyone can provide for this very
frustrating problem.

Cordially,
WFB

This seems to be a common problem because I have been experiencing this on
several sites both on single servers and load balanced server setups.
However, if you are having problems on a load balanced site I would advise
first trying the solution from Microsoft for this

Turn off EnableViewStateMac. The checksum is invalid across servers.
