Two ASP. NET 2.0 website servers were deployed using Server Load balancer.

When Server Load balancer is used to deploy two site servers, there are several problems and their solutions.

1. when you copy the published site file to the IIS Directory, prepare IIS support for the Framework, and visit the website, the Service unavailable word always appears, depressing .... search and find the solution:
Open the attributes of the IIS websites folder, and go to the service tab. Select Run WWW Service in IIS 5.0 Isolation Mode.
For example:


After this setting, our site can finally be opened on the local machine.

2. When configuring the second web server, complete the deployment and configuration according to the first step. Open the webpage and the following error occurs:This application has failed to start because the application configuration is incorrect. reinstalling the application may fix this problem. (exception from hresult: 0x800736b1)

A third-partyProgramSet to PDF-> XPS conversion. It is strange that the first server has no problems, and the deployment configuration is the same, including files being the same copy, but this error occurs on the second server. Finally, we found that the visual C ++ 2005 redistributable package is missing. After downloading and installing the package, the problem is solved.

3. the two Web servers have been configured and can be run locally. The following shows the domain name (pointing to the Server Load balancer) prepared in advance. The homepage is opened and the account password is entered for login, another problem occurred! Yellow Pages: Validation of viewstate Mac failed. if this application is hosted by a Web farm or cluster, ensure that machinekey > Configuration specifies the same validationkey and validation algorithm. autogenerate cannot be used in a cluster.

After searching and finding the solution, the Web. config was modified as follows:<System. Web>
<PagesEnableviewstatemac= "False" />
</System. Web>

Finally, everything is normal!
