BringerOD, can you post, or send to support, your web.config and server debuglog files, as well as additional information on how the web site / application is configured. Does the exception always occur when another user tries to connect?

I am still getting this error 3 times a day it seems.

Users are then not able to log in.

Anyone have any ideas?

I am getting the same error. I am using 7.5 as well.

I am user devforce 6.0.5.0.

Is there an update that fixes this. I am not sure if it is due to a login issue as above. The only way I fixed it is rebooting the server. I tried restarting the web site, then starting and stopping IIS, the reboot was the only fix.

Is there a later version than 6.0.5.0?

Here is the error.

Hi sbelini

I hate not knowing what caused it or how it was fixed. It's not in my nature.

As I said we're getting a new server in the next few days and IIS 7.5 will be my new best friend.

I just need to back off and be patient.

Hi George,

glad the issue is fixed.

Normally, the web.config/global.asax files would look different if deploying on IIS6 or IIS7.5 and that could be a good lead on pinpointing the issue. Well, it's gone now.

Hi

Upgraded to 6.0.6k and had one of our support people make some changes and it's now working as expected.

Not sure what the problem was or what fixed it.

I'm just happy that everything is running as expected.

Hi

DevForce Silverlight 6.0.6c (waiting for sales to send me the link for 6.0.6j)

I'm getting an exception on our IIS6 production server when more than one user tries to connect.

The first user can open as many browser sessions as they want but as soon as another user on another PC tries to login, bang, exception.

I've tested against IIS 7.5 and it seems to work okay. Not sure what could be different on IIS 6 (besides being OLD tech).

We have a new server coming in a few days but we have more EAP customers joining next week and I need to have a working solution.

Below is the exception copied from the Event Viewer.

WebHost failed to process a request.
