|
|
I am running a Windows 2003 SP1 Active directory. Both the forest &
domain functional levels are set at 2003. All clients are running
Windows 2000 SP4 & up. The above security setting is currently not
defined in the Domain Policy. I need to change that to level 5 (Send
NTLMv2 response only/refuse LM & NTLM) per KB823659. Will there be any
issues with doing that & do I need to make any changes at the client
level? Thanks |
