I've got the MCSA 2003 (290,270,291, 271 and 272)
I've jsut completed 2003 Exchange with a pass of 820. Its taken me a while but I am really happy

However I am somewhat worried that its almost out of date. Whats peoples view on this? Is it worth going for MCSE 2003 or just leaving the MCSA as it is and start doing other exams (I am thinking about exchange 2007 for instance as we have just upgraded to this)
Might even consider CCNA but thats a big leap.
Any help appreciated.
Thanks
Ben
