SQLConnection.Open() Timeout Error - but...nothing has changed?

[Nevyn Twyll]

I've been working on an asp.net application and everything's been great.
But suddenly, whether I'm tyring to use a database on my own machine, or on
my server, I'm getting a timeout when trying to open a database connection.
The error seems to happen regardless of what ASP.NET app I'm working
with/trying to debug.
It will open a few connections,

Here's the error:

Server Error in '/MyApplication' Application.
--------------------------------------------------------------------------------

Timeout expired. The timeout period elapsed prior to obtaining a connection
from the pool. This may have occurred because all pooled connections were in
use and max pool size was reached.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Timeout expired. The
timeout period elapsed prior to obtaining a connection from the pool. This

The connection string I use in my web.config is:

<add key="ConnectionString"
value="server=manwe;Trusted_Connection=false;database=MyDatabase;Application
Name=MyApplication;User ID=sqluser; Password=sqlpassword;"/>

Help?

Are you closing your connections after you've
finished retrieving or writing data with them ?

Yes - I just went through and made sure that was happening, and that my
datareaders were ComandBehavior.CloseConnection.

And the weird thing is, if I deploy the application to an IIS server, and
run it there, it seems fine....

Are you using XP as a Dev box ?

I think there's an issue with the max number
of connections available through XP.

Same for MSDE...
