You are unable to update the Normal Server. The Globally Unique Identifier (GUID) of the Information Server changes every time its service is restarted and the Normal Server renews the Information Server's GUID when the Normal Server's service is restarted.
If the Normal Server cannot connect to the Information Server, then the Normal Server may fail to update the Information Server's GUID. This results in a GUID inconsistency between the Information Server and the Normal Server. Thus, the Normal Server cannot be updated.
Additionally, when you check the tmudump logs in the Normal Server, it shows the following error:
Update program cannot get the source file from information server. Return code: 87
To resolve the issue, copy the GUID of the Information Server to the Normal Server:
- Open the Information Server (IS):
Get the IS GUID from the following location:
- For 32-bit OS, find the <IS GUID> from:
[HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ServerProtect\CurrentVersion\InformationServer] "GUID"="<IS GUID>"
- For 64-bit OS, find the <IS GUID> from:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\ServerProtect\CurrentVersion\InformationServer] "GUID"="<IS GUID>"
- For 32-bit OS, find the <IS GUID> from:
- Go to the problematic Normal Server (NS) and stop the Trend Micro ServerProtect Service.
- On the NS, copy the IS GUID to AgentGUID:
HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ServerProtect\CurrentVersion\RPC "AgentGUID"="<IS GUID>"
- Start the Trend Micro ServerProtect Service in NS.
- Manually deploy the update to NS using IS.
After doing the steps, a new update should reflect in the ServerProtect Management Console.
If the GUID inconsistency issue occurs again, then stop the Information Server from changing its GUID by adding the "GuidSwith" key to the Information Server:
- For 32-bit OS:
[HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\ServerProtect\CurrentVersion\InformationServer] "GUIDSwith"=dword:00000001
- For 64-bit OS:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\ServerProtect\CurrentVersion\InformationServer] "GUIDSwith"=dword:00000001
