I was in the middle of doing a SBS Migration from 2008 to 2008. After the new
hardware had installed SBS it said Exchange cannon be installed. I went to
add/remove programs and install it manualy but it gave me an error about
LDAP. I whent ahead and continued not paying attention and the installation
of Exchange was successful but was telling me it had no license key and had
180 days to get one. Well there is no license key that I know of as its part
of SBS so I tried the SBS key with no success. So I tired to uninstall
exchange but I got the following errors:

Summary: 3 item(s). 0 succeeded, 3 failed.
Elapsed time: 00:00:14

Error:
Setup encountered a problem while validating the state of Active Directory:
An Active Directory error 0x51 occurred when trying to check server
'SBSRAQ.enplan.local:3268' suitability: 'The LDAP server is unavailable.'.

Elapsed Time: 00:00:06

So now I want to uninstall exchange on the desination server and start the
migration over again but i get this error so it wont let me continue. How do
i get past this error?

I recommend that you post your question in an SBS newsgroup because they do
things differently, especially in the area of setup.
