30 second delay for all Admin Pages

Config:

Web Server:Dual 3.2 Xeon with 16Gigs Ram
Windows 2003 Enterprise SP2
Apache Web Server – 2.0.59
PHP 4.4.7
WordPress 2.2.1

mySQL Server:
Dual 3.2 Xeon with 16Gigs Ram
Windows 2003 Enterprise SP2
MySQL 4.1.22-community-nt

I’ve been running my WordPres blog for about 5 months now without problems. My Web server is on a stand along box and the mySQL server is also a stand alone box dedicated to the mySQL server. Both boxes are Massive in comparrison to the traffic my blog receives.

Problem:
My Blog is lightining fast when navigating to all my articles and pages of my site. A few days ago however I started having problems when accessing the admin pages such as wp-admin. The page loads however it takes ~ 30 seconds for the page to display. This is true for ALL Admin Pages such as Comments or write a post, user management etc… Any page accessed off the dashboard basically.

The odd thing is that the rest of my site used by my users is lightning fast. It’s only the admin pages. Like I said, each admin page takes about 30 seconds to paint…..

VERY ODD.

Any ideas?
