I am getting the timeout expired elapsed prior to obtaining a connection from the pool error on a winforms app compiled on VS2010 .net 4. I don't get this error on every computer using the program though. I can run the same process and only get this error on 2 out of 10 computers or so. All computers run remote, windows 7-10. SQL server 2008. I can't find any rim or reason to which ones work or don't work. I am using use statements in the code. What could I look for on the machines. I have 2 computers in one office, one works one doesn't. Both windows 10 64 bit. Same fire wall, and antivirus settings.
Any suggestions on what I might be missing.
