I had this exact same error earlier this week while trying to run Exchange
Admin from my Windows 2000 workstation. The Exchange Server is 5.5 Service
Pack 4. I couldn't for the life of me figure out what was wrong, I
uninstalled Exchange Admin, reinstalled it, tried only running Service Pack
3, then tried it using Service pack 4 and still no luck. Then I remembered
that the only thing I had changed recently was my password. My password
included the Euro symbol (Alt 0128) and a few letters after. So I changed
my password back to a standard alpha and numerical password and voila,
Exchange Admin worked. Your scenario is different, but this is what
resolved my DS_E COMMUNICATIONS PROBLEM ERROR. Try changing the password
and let me know if it works.

After adding a new Exchange server to my existing site, I get the above
error message when trying to duplicate a mailbox from one of the old
servers to the new under the following circumstances:
Exchange Admin on a WS connected to the new server gets the error.
Exchange Admin on a WS connected to the old server does not get the error.
Exchange Admin on the new server connected to the new server does not get
the error.
After getting the error message i can Cancel the duplicate mailbox
dialogue, but the mailbox is created and works OK.
I've tried Maximum Diagnostic logging on all Exchange components on both
the old and the new server and there is not a single Error message in the
Event Log and as far as I can see, the few warning messages had nothing to
do with the error.
I have since discovered that I can take an incremental backup of the
Exchange directory, but not the Private Information Store - again no error
messages in the event log. I can take a Full backup of both with no
problems. I use Tivoli Data Protection for Exchange and this returns the
message
09/19/2001 20:23:51 Backup of storage group Information Store failed.
09/19/2001 20:23:51 ACN5350E An unknown Exchange API error has occurred.
Has anybody any idea of where I should start looking for the source of the
problem(s)?
The old servers are all running NT4 Sp6a, Exchange 5.5 sp3. The new is
running W2K Sp2, Exchange 5.5 sp3. I have tried with Exchange 5.5 sp4 on a
WS admin with the same result.
