Please upload some line of code where you are getting error, we can help to you.

 open command prompt and run netstat -b -a will list all the port details.

 I will suggest, contact your network team to have a check.

@Kunal,

I am not finding the port in the asp.net tab.. I am using IIS6

Hi,

May be this is an issue with binding conflict. There is another application that is using port 80. If you change the bindings for the default website to 8080 [for test purpose] it will work.

You can run NETSTAT -ano in commant prompt and find out the PID for the process that is using port 80, then you can compare that PID with the process name in task manager[may be skype.exe?].

Or try this, just change the port from IIS -> Default WebSite(right click) -> Properties -> ASP.NET(tab) -> port ->

in this location change the port and click ok. May be this helps you.

i found a solved thread on net for same issue i think. you can check this..

@Prabhu Raja,

I have already checked all that but nothing is helping me

check out MSDN Support Documentation:

I am not an expert of this but i google about the error which you posted, this site says that the problem is because of the port number 80. hence check this link:

ERROR:The process cannot access tye file because it is being used by another process

Hi,

Please Elaborate your question in detail.

Hi..
     Describe your question in detail, when you did get error? 
 
 I am telling one case:- If you are using sql server db file (sampledb.mdf) then you want move or copy this file, it doesn't move or copy, in that case you should stop the process of sql server or kill the process of file using UNLOCKER software. Using that software you can kill process any file which is used by another process. If your case is different then inform me?
