Possible Errors

Error

Service unavailable

Resolution

This is one of the ever green errors we often used to get mostly because of service accounts. The common problem will be this account might not be a member of IIS_WPG group on the server or check IIS_WPG group have Read & Execute, List Folder Contents, and Read permissions to the Web site directories. So precheck with a network admin who is creating the service account for you whether the account has all the required permissions on the server.

Error

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (Provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

Resolution

Again, there may be several reasons, the most common is checking if the service account has access to the SQL Server. This error occurs even if you are not using SQL Server 2005, i.e. the same error occurs even if you use SQL Server 2000. Similar error occurs if there is any problem in the connection string too.

Error

It is not possible to run different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process.

Resolution

When we host multiple versions of ASP.net in a single server, we may get this error in event log. The problem might be an application pool will be associated with 2 different applications that use different frameworks. So isolating this application into a different App Pools will solve the problem.

Hi Satheesh Babu,
Really the Article was very good, to add your points, i have some suggestion during deployment.
There are some places, were Firewall is Mandatory and it cannot be disabled. In such condition, after giving appropriate Permission. Next step is to enable the Web Server(Http) in LAN Settings of the Firewall.

Goto Start --> Run --> type 'Firewall.cpl'.
Goto Advanced tab, in Local Area Network setting -> Click Settings.
After clicking Settings, you will get the list of services. Check WebServer(Http) is checked or not.
After checking WebServer only, your WebSite can be accessed from Other Machines.

Thanks and Regards,
Prabhu

Hi guys,
Thank you so much for the valuable feedbacks!!!
Pramod:
I think you havn't installed IIS 6.0.IIS 6.0 is default websrver of windows 2003 and it will come with Windows 2003.I guess you are trying to do something in your desktop PC(like 2000 or XP). App pool concept is there only in IIS 6.0.

For your info:
Windows 2000 ---> IIS 5.0
Windows XP ---> IIS 5.1
Windows 2003 ---> IIS 6.0
