Web Farms and View State Problem

When deploying a web application from one server to another you may come acroos this error... System.Web.HttpException

Encryption of data storage in viewstate will be based on server's MAC Address..We can avoid this error by setting enableViewStateMac to false.

Using enableViewStateMac requires that successive requests be forwarded to the same server (i.e. server affinity). This feature is used to help prevent tampering of a page's view state; however, it does so based on an auto-generated validation key on the current server. From this key, a message authentication code (MAC) is generated and sent in the ViewState back to the browser. The problem is that if a POST back is performed and goes to a different server, you will get a nice little error message saying “Corrupt View State“.

To fix this, you can either set enableViewStateMac to false in the element or specify a common value for the validationKey attribute in the element across all servers (in the farm).

By the way, documentation says that this is OFF by default. That is incorrect! Go check machine.config!

Increase concurrent connection limit in IIS

Increase the 10 concurrent connection limitAre you getting 403.9 "Access Forbidden: Too many users are connected" errors on an XP Pro website? You're limited by default to 10 concurrent connections by design, but this can be increased. First, make sure your default windows script host is set to the console (cscript.exe) one.

cscript //h:cscript

Next, let's increase the connection limit to 40.

C:\Inetpub\AdminScripts\adsutil set w3svc/MaxConnections 40

Note that this is a hard-coded limit; it can't be increased any further unless you like patching windows system files. You can, however, make the IIS connection timeout more aggressive so connections don't last as long.
