Validation of viewstate MAC failed.

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.



Hello Friend, I have face this issue many time on online live website project.

Solution : 

Set the machinekey in the web config file.

If you want to generate the machinkey as per .net framework or see the below generated key.


Framework version

Asp.net 1.1

<machineKey validationKey="4B6124F1A96C1D90C2EB5298094895EBB9B1AB2227971EAC82E46D6E9B3E9
76CE56A7629E8C4E6C1AEF7A3B4F47681B60119D792EA47613971729564072DEB2A"
decryptionKey="4DD6849D7B818F86F6566B4AEDF1A9BD134DA1994236F8B8"
validation="SHA1" /> 

Asp.net 2.0

<machineKey validationKey="713BBE182A80928A389952B90A305817D43D87DF110B8F1BF4CF3D5628013F
