    Hi Team,

    I am getting error while tring to Check in any document in Sharepoint 2007. Error - "Unable to validate data. System.Web.Configuration.MachineKey.GetDecodedData(Byte[] buf, Byte[] modifier, Int32 start, Int32 length, Int32& dataLength). Anybody please let me know how to resolve the issue. It has affected our 9 site collection with almost 2000+ sites. Please email me your your suggestion or you can share your ideas here also.

    Tried to reset the IIS, checked the Internet connection speed (8MBps). Cleared the cache and all but no luck.

    Thanks,

    Pronob

    Hi Hemendra,

    Thanks for your reply !!

    I have checked the provided solution mentioned in the support site. But the entire system was stable for almost 4+years suddenly users faced the issue. Is there any other solution is available other than installing Sp in VM. Is there any configuration settings can help ? Please help.
