Having difficulties in getting email to be sent as alert.

We have the following setup:
NT 4.0 firewall management server(server A) and radius server (server B) in
a workgroup called ABC
Excahnge server in Nt 4 domain called exch01

i can get email running on server A as nt auth disabled hence i'm asked for
user id, domain and password when opening outlook.

having difficulties within BENT to get my profile actice. have made profile
name, user account all the same, but i'm not asked to specify a domain name
when setting up email alert in bent.

Any Ideas?
thanks in advance.
