Hi,
I am getting this when I run it on asp.net 2.0 but works find on asp.net 1.1

Validation of viewstate MAC failed. If this application is hosted by a Web
Farm or cluster, ensure that <machineKey> configuration specifies the same
validationKey and validation algorithm. AutoGenerate cannot be used in a
cluster.

Please help. Thanks.
 
Had this problem also once

Funny thingy was that the webserver at the provider wasn`t a cluster and
also that my code did not changed from when it did work without anny
problems

So after the provider blamed me , my code would probably have an error etc
etc ( those dumb techy`s :-) ) i asked them to put my project in a
sperate application pool as i thought that probaly other projects running in
the same app pool interfered with my program , so they did and the problem
was solved .

After doing some investigating on the web i understood that it had something
to do with the parsetime of the webserver, however in my situation probelm
was solved with a seperate app pool \
so i recomend you to try this option out
