I have a small network, one 2003 DC (file and print server) and 15 workstations. I have decided adding a seperate windows 2008 R2 with exchange 2010 and I did. Now I am able to send and receive an emails without any problem. However, I have an issue that is certificate. Since I didn't expect the exchange server, I used domain name abc.com (for example) but acutual domain name is abcxyz.com so I got a certificate from godaddy.com for abcxyz.com but abc.com. This gives me some issue. First I am getting security warning whenever I open outlook. I just hit yes or no then it opens outlook no problem. I also realized that out of office assistant is not working for all workstations. I think this is related to the security.
What is my best solution for this at this moment? I cannot reinstall both servers.
Do I have to install ceriticate server on exchange server? If so, please let me know how to.
Thanks in advance
