I have two Windows 2008 R2 Servers, same domain. One ACDC1 and one ACDC2.
The Default Domain policy has Complexity Requirements turned on.
I used this password Ihatewindows1!!
It did not like it. Said it was not complex. Why not?
1 uppercase, 1 lowercase, 1 number and 1 symbols and over 8 characters. Also have never used that password. This one is an example, I have 4 users all saying they cannot change passwords with stuff ranging from passwords like Yellow01 to Elliott01to D@nteventrY
None of those worked. New domain so rememberd passwords should not matter.
5 Password remembered, 90 Days to change, 1 day min. password age, 8 character length.
I disabled Complexity Requirements and did gpupdate and rebooted multiple times. Still require complex password. All replication between DC works fine.
Thanks!
