A few days ago I was working on a repro I got from a customer as I very often do, and for some reason after a while my IIS started to behave oddly, pages where not served, the application pool was stuck doing \u201csomething\u201d and whenever I tried to open the IIS Manager I got the error \u201cThere was an error when trying to connect. Do you want to retype your credentials and try again? Cannot create a file when that file already exists\u201d:<\/p>\n

\"Failed
Failed to connect<\/figcaption><\/figure>\n

Needless to say that being IIS on my local machine and I have not made any changes to the security\/ACLs\/DCOM etc\u2026 there should be no need to retype my credentials; and by the way, even retyping them did not help.<\/p>\n

By the way, if I tried to remotely connect to another machine of mine, I got the message \u201cThe type initializer for \u2018Microsoft.Web.Management.Remoting.HttpChannel\u2019 threw an exception\u201d:<\/p>\n

\"Type
Type initializer throw an exception<\/figcaption><\/figure>\n

My next step has been to try to restart the World Wide Web Publishing Service: it was (oddly?) stopped, but again I got an error \u201cWindows could not start the World Wide Web Publishing Service service on Local Computer. Error 1068: The dependency service or group failed to start\u201d:<\/p>\n

\"The
The dependency service or group failed to start<\/figcaption><\/figure>\n

The W3SVC service has a dependency on WAS<\/a> (Windows Process Activation Service), I tried to start it manually and got \u201cWindows could not start the Windows Process Activation Service service on Local Computer. Error 183: Cannot create a file when that file already exists.\u201d:<\/p>\n

\"Could
Could not start the WAS service<\/figcaption><\/figure>\n

That is the same message I got from IIS Manager, so I thought to have a look at the event log to find out more: I was wrong! I got \u201cMMC could not create the snap-in. The snap-in might not have been installed correctly\u201d:<\/p>\n

\"MMS<\/a>
MMS coult not create the snap-in<\/figcaption><\/figure>\n

I quickly found out that virtually every MMC snap-in was broken on my machine (\u201cServer Manager\u201d \u201cCertificates\u201d, \u201cLocal Users and Groups\u201d, just name one) but why?!?\u00a0 ?<\/p>\n

Well\u2026 on Windows 2008, MMC is based on .NET as of course is IIS and when the problem first appeared I was tampering my machine.config file to try different ThreadPool settings\u2026 ?<\/p>\n

The golden rule in computing reads \u201cAlways back-up sensitive data!\u201d\u2026 after restoring my clean machine.config all the problems above went away! ?<\/p>\n

For curiosity I had a deeper look at it and found the following lines:<\/p>\n

\n
<<\/span>system.web<\/span>><\/span>\n\n        <<\/span>processModel<\/span> autoConfig<\/span>=\"true\"<\/span>\/><\/span>\n\n        <<\/span>processModel<\/span> autoConfig<\/span>=\"false\"<\/span> minWorkerThreads<\/span>=\"100\"<\/span> \n            minIoThreads<\/span>=\"100\"<\/span> maxWorkerThreads<\/span>=\"404\"<\/span> maxIoThreads<\/span>=\"404\"<\/span>\/><\/span>\n\n        <<\/span>httpRuntime<\/span> minFreeThreads<\/span>=\"152\"<\/span> minLocalRequestFreeThreads<\/span>=\"152\"<\/span>\/><\/span>\n\n[...]<\/pre>\n<\/div>\n
Easy to spot it now, eh? For my repro I had set autoConfig=\u201dfalse\u201d but then I decided to set it to \u201ctrue\u201d, for some reason I added a new <processModel><\/a> element with its own autoConfig=\u201dtrue\u201d and forgot to remove the \u201cold\u201d <processModel>\u2026 At least I learnt something new from my foolishness! ?<\/p>\n
Note: there might be other reasons if you get the errors above, but always keep a clean backup of your configuration files at hand, just in case\u2026<\/em><\/p>\n
