Hello. I have a client who is experiencing problems with an application running on a Windows 2008 R2 server. I've done packet captures of a successful application launch and a failed launch. Here's the error (packets copied from MS Network Monitor):
1725SMB:C; Nt Create Andx, FileName = \ICONS\FONTS.SP211:50:14 AM 4/5/20139.2890620System10.10.10.310.10.10.1SMB{SMB:116, NbtSS:7, TCP:6, IPv4:5}
1811SMB:R; Nt Create Andx - NT Status: System - Error, Code = (67) STATUS_SHARING_VIOLATION11:50:15 AM 4/5/201310.3007810System10.10.10.110.10.10.3SMB{SMB:116, NbtSS:7, TCP:6, IPv4:5}
The server is IP 10.10.10.1, the client is 10.10.10.3.
The application vendor says we're the only ones experiencing this problem. It happens intermittently; the app may launch successfully 100 times in a row before failing. Once it fails there's a good chance it will fail again. It fails more frequently later in the day when more people are using the app.
This error never occurred prior to migrating the app from a Windows 2003 server to 2008 R2. We upgraded the application at the same time as the migration.
Is there anything I can change in the server to resolve this problem?
Thanks in advance for your help.
