Don't give up, read this article and make changes as suggested. http://support.microsoft.com/kb/221790
1. If you are running Windows 2000, install the post-SP1 hotfix described in the following Microsoft Knowledge Base article to both the IIS servers and the file server:
271148 (http://support.microsoft.com/kb/271148/) MaxMpxCt and MaxCmds limits in Windows 2000
2. Increase the values of MaxCmds on the IIS Servers and MaxMpxCT on the File Server by using the following registry scripts:

Save the following registry script as Client.reg, and then run it on the IIS servers:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters] "MaxCmds"=dword:00000800
Save the following registry script as Server.reg, and then run it on the file server:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
"MaxMpxCT"=dword:00000800
"MaxWorkItems"=dword:00002000
By default, these scripts specify a MaxCmds and MaxMpxCT of 2,048, which should be sufficient for most situations. MaxWorkItems has been specified at 4x MaxMpxCt or 8,192. For more information on these settings, see the "More Information" section of this article.
3. Restart all of the IIS servers and the file server for these changes to take effect.

Thank you for the post....  unfortunately I had already tried this.  This was "fixed" in Win2k sp2 I believe... I have sp4 installed.  I did however try the values suggested in your post (didn't work, same error), but also bumped them up to 65535 (max suggested) and it still came back with the same error.  Also did an iisreset before trying each time.

So far....  file replication is working very nicely using the ViceVersa program.  It does cost some money, but IMO it's worth it so far.

IISreset won't effect the changes applied to the registry. You need to reboot.

Using Web Farm Support - Alternative Configuration

In the Web Farm Doc (downloaded with 4.4), Page 9, Alternative Configuration:

- Open the following file in Notepad:  "$root\Providers\CachingProviders\BroadcastPollingCachingProvider\Providers\SQLDataProvider\03.01.00.SqlDataProvider"

This path and SqlDataProvider file no longer exists in a default source installation of DNN4.4

Is it no longer needed for the alternative configuration setup (using file replication services)??
