I have seen info on the microsoft nntp server saying that sp3 absolutely
does not work with sp3.   All the documentation I have seen (through
rigorous searching) says absolutely do not run compression on exchange
2k and to honestly not run it on windows 2k server.   Compression is ok
for win2k professional but it's a resource hog in the server environment
and can lead to disk channel bottlenecks.  

Of course I found all this out after running Win2k and Exchange2k on a
compressed system while researching information about installing service

Even when I get it all uncompressed there is no way I am installing sp3
from everything I have read about it.  I think I will wait till the
roll-up package for sp3 which is guaranteed with any ms product.   

:(  I should have installed groupwise.

Thanks for the response Andrea.

You may be right about the compression, but having uncompressed the
files on disk it made no immediate difference to our exchange system
(which has been running quite happily for 14 months and had SP1 & SP2
applied without problems). We have now re-installed Exchange 2000 and
then Exchange SP3 and all except one mail store then mounted and ran
(and the one which didn't run has now been fixed with ESEUTIL).

Two additional points worth noting.
1) Dispite having re-installed the original Exchange 2000 system
(confirmed as not having any SP in System Manager) it would not allow us
to install earlier SPs. So there does not appear to be any way to
roll-back an Exchange SP.
2) If Exchange SP3 does not support mail stores which are compressed
(although earlier versions apparently do) - WHY DO MICROSOFT NOT WARN OF
THIS IN THEIR SP3 RELEASE NOTES?  (or mention it on their website!)
