Job A from the phone interview I came to understand that I would be dealing with things such Active Directory, IIS, Exchange 2003/2008, POP3/SMTP, firewalls and such.

Job B is with Citrix, which I have come to understand is a viable form of network to learn.

So if both jobs were to offer the same benefits and pay, which would be better to pursue based solely on the experience you would gain?
