This type of problem is difficult to diagnose without the proper background information from the customer. In this scenario the customer was using Regex to filter for system computer names.
- configuration 1: Computer Name = | Regex=^(svp|svmp).*
- configuration 2: Computer Name = | Regex=^(sv(?!p|mp).*)
Config 1 worked fine, while config 2 was failing to apply to any systems that matched the criteria in the regex filter.
We established that this was not the problem after explicitly using the filter: Computer Name = | "actual_machine_host_name", as this did not work either.
