How to tackle error with Wamp/Xamp server??
Make sure no other program conflict wamp such as Xampp, phpEasy, IIS, Skype, Zonealarm, firewall/antivirus, NOD32, Eset, any web and/or Remote Desktop related program, such as Teamviewer ...
- Server Error in Application "DEFAULT WEB SITE"Internet Information Services 7.5
IIS and Apache/Wamp are both web server and might conflict in some way, so you have to disable IIS in order for Wamp to work
Disable IIS in Vista/W7:
Control Panel, Uninstall Programs, Turn Widows Features On or Off, uncheck Internet Information Services
Disable IIS in XP:
Control Panel, Add/Remove Programs, Add/Remove Windows Components, uncheck Internet Information Services (IIS)
Restart computer, then restart Wamp
Also, in folder C:\WINDOWS\System32\drivers\etc, open file hosts and delete anything in this file and have only this line below and nothing else
If using Skype, go to Tools->Options->Advanced->Connection and uncheck the box "Use 80 and 443 as alternatives for incoming connections". Restart Skype after WAMP. Now you will be able to use both programs at the same time w/o problems
