I just installed exchange 2003 enterprise edition, when i try to apply sp2 for exchange it error out. I have use SP2 for exchange 2003 standard edition but this sp2 will not work for enterprise edition. Is there separate sp2 for exchange 2003 enterprise edition? Please take a look at the error message when I try to apply sp2.
