DLL Hell is nothing but overwriting the dll in the registery. If two application are installed on a single server, one installed First and the Second Installed Later and There is a dll with same name with different functionality used in both the applications, So in this case Application one works fine all the days until application two Installed on the machine. Once the Application two is installed containing the DLL with the same name as Application one Contains then In this case the application one Fails as the DLL from Application two overwites the DLL of Application one in the Registery. So Application two works fine where as Application one Fails as the DLL is missing.
