IIS7 Upgrade from IIS5.1 with out URLScan
I assume, after upgrading your IIS5.1 box, which was happily hosting your personal web site for last 5 years, to IIS7.0, no more works. Not to worry, check the following few things and you should be able to get back working web site again.
Keeping security threat in mind, we have taken some security steps to prevent any malicious attack by the “not so good internet citizens” on your box. If you did not have URLScan installed with your IIS5.1, then on upgrade, IIS services will be disabled. You can start IIS Admin UI (inetmgr.exe) and a pop up should appear with the right set information on why and what services are disabled and how to enable them. The same set of services will also be disabled if you had Front Page Server Extensions installed on your XP install. Mainly the following services will be disabled.
1> World Wide Publishing Service (w3svc)
2> IIS Admin Service (iisadmin)
3> Microsoft FTP Service (msftpsvc)
You can simply go to services.msc (start > services.msc) and enable the above mentioned services first and then start them OR simply type the following lines in a command prompt
SC CONFIG <service name> start= demand
NET START <service name>
You can use RequestFiltering module in IIS7.0 in the place of UrlScan tool and configure your server appropriately.
