Mason - Thanks for all the help. Actually your previous email with those troubleshooting commands helped me find the problem. Once I discovered I could not telnet on port 3306 to the remote server I found that port 3306 on the database server was only open to one IP. I changed the IP to the new one and telnet worked. I then tried connecting to the remote database from a client using the mysql command you suggested and still could not connect. I looked to see if any linux firewall rules were enabled on the remote database server and found everything to be locked down to only allow communication from one server. I updated the rules with the appropriate IP and everything started working again. Thanks again for pointing me in the right direction.
