We have an asp.net application which consumes WCF service developed by any 3rd party vendor. In most of the cases it is working as expected, but sometimes it is giving "The system cannot find the file specified" error.
Environment details:
- Application Developed in ASP.NET 2.0 + .NET3.5
- Host: IIS 8.7 + Windows Server 2012;
- AppPool: Running with a domain service accounts
- WCF Client - Using nettcp binding with TransportWithMessageCredential security using Certificates
- WCF Client - Certificate store : Current User\My (AppPool domain user has Certificates in Current User Store)
Issue:
- Sometime getting "The system cannot find the file specified" error
Questions:
- Is it issue at Service Host Or at Service client?
- What is the root cause for it?
- what are the possible resolutions?
I greatly appreciate any help in resolving the issue.
Thank you.
