I am unable to sync my BM server with an internal time server after upgraded
the server.

Config Prior to Upgrade
NW 6.0 SP5
BM 3.7 Sp2
Edir 8.7.0.3
Nici 2.6.4

Config After the Upgrade
NW 6.0 SP5
BM 3.8 Sp3 & also applied IR 2
Edir 8.7.3.4
Nici 2.6.4
TCP610l.exe

It syncs time with an external time source if I change the time sync type to
single. I have 10 other servers that are able to sync time with my internal
time source.

Here is a copy of timesync.cfg

Configured Sources = ON
DEBUG = 7

Polling Count = 3

Polling Interval = 600

Service Advertising = ON

Synchronization Radius = 2000

Type = SECONDARY

NTP Client Port = 0

# TIMESYNC Configured time source list

TIME SOURCE = 10.75.75.10:123
