How Can I troubleshoot “Attempted to read or write protected memory” error on a Web Service?
Hi ,
I have web service that needs legacy third-party API with very limited logging options.
Public Shared Function DoJob(
<In> ByVal FName As String,
<Out> ByRef directoryDN As IntPtr,
<Out> ByRef directoryPassword As IntPtr) As Int16
End Function
The API is 32bit compiled so I created my web service as 32bit application. The web service application target framework “.NET Framework 3.5” and it has been working for few years on server 2008 and server2012. We want to migrate to server 2016, but every time I call the service and I need to use some of the API functions I get “Attempted to read or write protected memory” error. I fallowed the same steps installing the application, as I did on the two old servers.
1) Created New ApplicationPool named “NET2” .NET CLR version v2.0.50727
2) “NET2”-> Advanced setting -> Enable 32-Bit Application -> True and Managed Pipeline Classic
3) Created new web site and assigned NET2 AppPool to it
4) Created new folder and Converted to Application
5) Installed the web service to it
6) WebSite -> Edit Permissions->Security->Add and I add “IIS AppPool NE2 “ Full Control ( just a test )
7) WebSite ->Authentication-> Anonymous Authentication -> Edit -> ApplicationPool identity
8) Added API dll path to Environment Variables Path
After two days of permission and policy comparison between server 2012 and the new server 2016
Every time a call the service I get “Attempted to read or write protected memory”.
Some steps I try to resolve the issue.
1) CasPol.exe -m -ag 1.2 -url file://path/path/* FullTrust
2) %windir%Microsoft.NETFrameworkv4.0.30319aspnet_regiis.exe –i
%windir%Microsoft.NETFramework64v4.0.30319aspnet_regiis.exe –i
%windir%Microsoft.NETFrameworkv2.0.50727aspnet_regiis.exe –i %windir%Microsoft.NETFramework64v2.0.50727aspnet_regiis.exe –i
3) ICACLS "C:pathpath" /grant "IIS AppPoolNET2":F /t
ICACLS " C:pathpath" /grant "IIS AppPoolNET4":F /t
ICACLS " C:pathpath" /grant "IIS_IUSRS":F /t
4) Created console application using source code of the web service and ran it from the same folder as the web service using the same dllimport statements ( worked perfectly )
5) Used “Wireshark” ( request and responses are executed )
6) Used “Promon Application” to compare server 2012 and server 2016 processes , everything is similar but a call to w3wp.exe
FASTIO_NETWORK_QUERY_OPEN C:WindowsMicrosoft.NETFrameworkv2.0.50727VERSION.dll FAST IO DISALLOWED

…….
Followed by my web server log file with exception “System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt”
Any Ideas.
