I have a cell manager that has been running with no issues for several years.
1 - It's running on Windows 2003 and supports 10 Windows cells.
2 -All cells have encrypted communication enabled.
Symptoms:
1 - Only the cell manager can pass "check installation"
2 - NSLOOKUP works both ways on all servers. All servers are in the same domain.
3 - When I run omnicheck -dns -host hostname -verbose, the utility will starts to parse the cell listing and just sits there.
4 - TELNET 5555 connects but rarely returns expected disconnected response.
5 - I've disabled the Windows firewall but no change.
6 - Cleared the \tmp directory.
