All, is it possible in AD to set a *dictionary* setting i.e stop people using dictionary words for passwords? Also is there any setting for *special* characters.....

A site that my company maintain have asked for and I qoute *an 8 character password with letters, numbers and special characters and with dictionary control, and to chnage it once a month* most of these are obv fine for me to implement, its just the special characters and dictionary bit that Im not sure about

I dont know what there users are gonna say, seems a bit OTT to me, but not for me to question...

See http://support.microsoft.com/default.aspx?scid=kb;en-us;225230 how to enable complex passwords in Windows 2000 AD.
If you want to modify the behavior you probably need a custom Passfilt.dll.

Hope it helps,

Enabling password complexity requirements will "sort of" take care of the dictionary business, as you won't find words with numbers in them in a dictionary ...
For a more refined version of password control, you can have a look at Anixis' Password Policy Enforcer, which allows for defining your own dictionaries and complexity requirements, without the need to program your own passfilter dll.
