Hi All, I have created a service with a start value = 2 (SERVICE_AUTO_START). The service calls the Windows function WSAStartup which initates the use of the Winsock.dll. If I add my service to a group I can control when it gets started by adding it into the following list that is in the resgistry under: /HKLM/SYSTEM/CurrentControlSet/ServiceGroupOrder. Most of the groups in the list contain services that contain a start value of 0 (SERVICE_BOOT_START) or 1 (SERVICE_SYSTEM_START). The higher a service in the list the sooner it loads. All the groups with a 0 get started first, then the groups with a 1 and then the groups with a 2. So, a group that contains a service with a start value of 1 that is high in the list will not start until all the groups with services that have a start value of 0 get loaded. Please see: http://support.microsoft.com/kb/115486 My question: if the service I have created calls the Windows function WSAStartup (start value of 2), where in the ServiceGroupOrder List can I place it so I would be sure that the proper services have already been started to support the WSAStartup function call? Thanks in advance, - Tom

I think I would be investigating the "DependOnGroup" or "DependOnService" entries features and nominate an appropriate service (ie: winsock or winsock2) as the dependency for your service. Your service then will not start until after the winsock reports start successful. You may also want to build a bit of a time delay into your service before it attempts to make any calls. I have seen some services that do not like having calls made of them IMMEDIATELY after they start (test your situation and see what happens) - you can trigger some really weird behaviours like race conditions - I don't know whether the winsock would be in this category.
