Have you tried the url encoded string.

In case anyone runs into a similar problem, a friend mentioned how I might
be able to use url encoding to pass the required character for this.

I ran over to http://www.ascii.cl/htmlcodes.htm and ! is 21, so a simple
change to the command to read:

check_command check_http!-S -u /post.html -P
username=abc&password=%21ab2%21)z%21 -s status

WORKS! :)

Thanks for the input from everyone.
