IIS AppPoolIdentity and file system write access permissions

Question

Here\'s an issue with IIS 7.5 and ASP.NET that I\'ve been researching and getting nowhere with. Any help would be greatly appreciated.

My question is: using ASP.NET

Answer 1

I tried this to fix access issues to an IIS website, which manifested as something like the following in the Event Logs → Windows → Application:

Log Name:      Application
Source:        ASP.NET 4.0.30319.0
Date:          1/5/2012 4:12:33 PM
Event ID:      1314
Task Category: Web Event
Level:         Information
Keywords:      Classic
User:          N/A
Computer:      SALTIIS01

Description:
Event code: 4008 
Event message: File authorization failed for the request. 
Event time: 1/5/2012 4:12:33 PM 
Event time (UTC): 1/6/2012 12:12:33 AM 
Event ID: 349fcb2ec3c24b16a862f6eb9b23dd6c 
Event sequence: 7 
Event occurrence: 3 
Event detail code: 0 

Application information: 
    Application domain: /LM/W3SVC/2/ROOT/Application/SNCDW-19-129702818025409890 
    Trust level: Full 
    Application Virtual Path: /Application/SNCDW 
    Application Path: D:\Sites\WCF\Application\SNCDW\ 
    Machine name: SALTIIS01 

Process information: 
    Process ID: 1896 
    Process name: w3wp.exe 
    Account name: iisservice 

Request information: 
    Request URL: http://webservicestest/Application/SNCDW/PC.svc 
    Request path: /Application/SNCDW/PC.svc 
    User host address: 10.60.16.79 
    User: js3228 
    Is authenticated: True 
    Authentication Type: Negotiate 
    Thread account name: iisservice 

In the end I had to give the Windows Everyone group read access to that folder to get it to work properly.
