I would say "No". No offense to all you MCSE's out there, but I just replaced an individual that was an MCSE/MCDBA. I too am
only CompTIA A+ certified (for now anyway) and had to do a lot of cleanup from what they had done. This person took a crash course and in one month became an MCSE (I believe the term is "Paper MCSE"). It showed and the people that employed this person are now wondering why they gave this person a raise for having such certs. I am in the works for getting CompTIA N+ and then CompTIA Security+
I would advise the same Wombat, if you're going to learn N+ and Security+, you're more than likely going to learn it in a Win* and *nix environment. Don't limit yourself to just Win*.
Now, all you MC's can call me names.
