I have setup an ACT Pro 2011 database for 4 users. The file is on the network server & it works well until the Administrator shuts down his laptop. It still works when he exits ACT, it's only when he exits the system do the users lose access. I have followed all the suggestions found in the Knowledgebase (Answer ID 19640) i.e. a) share database enabled, b) Folders permission c) run services.msc re SQL Server Browser & ACT7, d) TCP/IP protocols etc. Could it have anything to do with Citrix? The point is that it all works smoothly with no problems until the Administrator shuts down. I have even upgraded the users' security levels to Manager with no success. Has anybody struck this before & if so how to fix?
