Dotnetpanel Forums

Hi,

I use DotNetPanel 2.8 and MailEnable 2.52.  Both serves have DotNetPanel 2.8 on them.  This was working until I upgraded.

When a new mailbox is added, either as a customer or the admin account, the system says it is adding it, waits a while, then returns to the list of mail accounts, but it is empty.

 The following error appears in the logs:

The underlying connection was closed: An unexpected error occurred on a receive.

MailEnable 3.62 Standard  (fresh install from few minutes ago), and DNP 2.8.3

Same Problem, with a different error:

If you are running Windows 2008 x64 please put this setting ‘Enable 32-bit application’ – true. These settings are located under Dotnetpanel Server Application Pool.

The answer was provided by Andrey Severtokov from DNP (thank you Andrey  ).

Excellent! I had the same problem and this has fixed it. Go to Application Pools in IIS7 and change the value in advance settings for the DNP server application pool. set allow 32-bit apps to True.

Thanks everyone.

WARNING!  Changing this setting will cause most of DNP 2.8.10 to break if you are running windows server 2008 R2 x64

Great... so what is the fix under 2008 R2 x64?

You need to set the Dot Net Panel Server Pool to Enable 32-bit applications (true). 

See my post here: http://forum.dotnetpanel.com/forums/p/7219/29265.aspx#29265

In 2.8.11 they have fixed the problem in which you had to switch back and forth (as outlined in the link/post). 

I can't create mailboxes from DNP in 2008 x64.

I've set DNP Server Pool to run in 32-bit and it doesn't work.

There is a case where this won't work.  Did you see the DNP method located here: http://forum.dotnetpanel.com/forums/p/7219/29265.aspx#29265
