We built the www.nrl.com site on DNN 4 with 3 web servers a clustered file server and clustered SQL boxes. (The site does 17 million pages a month) We ran inot some permissions issues with using the separate file zserver which houses all of the files needed to run DNN. The fix is below.
As far as I can tell, the issue your experiencing is the result of the default .NET Code Access Security (CAS) permissions not allowing remote code to execute. This issue is described in the following Knowledge Base (KB) article. This article hasn't yet been updated for .NET 2.0. The error looks a little different on .NET Framework 2.0 and unless you have the .NET 2.0 Framework SDK installed, you won't have access to the Microsoft .NET Framework 2.0 Configuration MMC to make the required change, so I've included the equivalent caspol command below:
PRB: "System.Security.SecurityException: Security error" Error Message when the Virtual Directory Points to a Remote Share in ASP.NET

caspol -m -ag 1 -url "file://\\fileserver\share\*" FullTrust -exclusive on

Re: Code Access Security Issue for web farms with a separate file server
Philip,
Congratulations on that fantastic site!
It is great to hear DNN4 being used for such a high-profile, high-trafic website.
Your Member signup process looks really cool, is that a completely custom solution or did you use any 3rd party module like UCanUse or Datasprings?
Also great info on the CAS issue.
I have been making a DNN websites directory and so have studied hundreds of DNN websites and this site is my favourite!

Very cool site Phil. Now you just need to get the rest of BigPond to see the light ;).

The member sign up is a modified version of the DataSprings system. Its fairly heavily modified to make the wizard. Works well though.
I nearly got DNN into Telstra Wholesale last year. That would have been awesome, 100,000 sites they were looking it.

Re: Code Access Security Issue for web farms with a separate file server
We actually had to scrap the dynamic registration product as it has some flaws in field validation, layouts and a few other issues. In the end we hand coded a form (1 day effort) as opposed to spending 4 days trying to get the dynamic registration add on production ready.
Basically, dynamic registration was not going to scale, however I understand there is now a new release from them, but we have not looked at it.

Modules used in NRL site
Hi Philip,
I met you once at Department of Treasury & Finance in Victoria. NRL site looks great. Could you let me know what modules/3rd parties you used for this site. I can read you have actually customised some of those modules.
From above - a customised datasprings, looks like tab aggregator (dnnstuff), and the others?

Re: Code Access Security Issue for web farms with a separate file server
Thanks! I just completed testing for a web farm DNN deployment and this posting solved the last hurdle I was trying to get over. Thanks again so much!
