Good day all, I've set up this Windows Server 2008 R2 HPC Edition with Service Pack 1 (x64) - DVD (English) but after I've put one 12-alphanumeric password (such as "testab123456") for the first time I access it, it says "Unable to update the password. The value provided for the new password does not meet the length, complexity or history requirement of the domain." Why? Many Thanks & Best Regards, Hua Min

Symbols must be on both registers - upper and lower: in Your case - TestLab123456, for example.

Thanks for time and efforts.
