Cannot connect to MySQL, error #1130

[Tony Rogers]

I am new to MySQL, as this form implies.

I have recently installed MySQL 4.1 on a Win2000 IIS 5.0 Server. This server is hosted on a closed IntraNet, so I am not worried about security and have set it up using the default login ("root" with no pw. I was planning to change this once I get it working, but I can't yet connect.)

I have tried to connect to it using PHPmyAdmin, MySQL Administrator, and the MySQL Command Line Client.

My errors are as follows:

:: PHP MyAdmin____________________
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in config.inc.php and make sure that they correspond to the information given by the administrator of the MySQL server.
Error

MySQL said: Documentation
#1045 - Access denied for user 'root'@'localhost' (using password: NO)

:: MySQL Administrator____________________
MySQL Error Number 1130
#HY000Host 'uhc-170.umd.edu' is not allowed to connect to this MySQL server

If you want to check the network connection, please press the Ping button
(Ping seems okay, I get "Reply from 128.8.222.118: Time=0ms TTL=128" repeatedly)

:: MySQL Command Line Client____________________
Since we are on a closed IntraNet, I simply set MySQL up with the default user/pass settings (root/no pass). I hit enter when prompted for password, and the window beeps and instantly closes. In the fraction of a second before it closes I can read "Error 1045" again.


I'm baffled, and I have pored over forums for hours with no success. Is anybody able to help me?
