Changing Data Directory (no replies)

Hello,

I am trying to change the data directory to point to a new lun.



I shutdown service and added the directory in My.ini.

#Path to the database root
#datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/"
datadir="R:/MYSQLBackup/Data/"


when I restart the service and try to connect via workbench. I get the following error in err log where I moved the data directory (R: Drive)

120622 10:26:16 [Note] Hostname '[hostname]' has the following IP addresses:
120622 10:26:16 [Note] - [I.P. Address]

I get the following workbench error when I attempt to login:

"Your connection attempt failed for user 'root' from your host to server at [I.P]:3306:
Host [I.P.] is not allowed to connect to this MySQL server.

FYI - This is a windows environment.

Thanks
