Hi there
Some of the end-users access our webswite and got the 'System.IO.IOException: Invalid Signature' exception. Hard to figure out why this 'Invalid Signature' error comes out.
Environment : Windows 2012 + DFS feature enabled. The C# program tried to access the file under the DFS folder.
Following is the exception stack:
System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IO.IOException: Invalid Signature. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at
System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean
checkHost) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode
mode, FileAccess access).
Can anyone please shed a light on this issue.
Thanks.
