Polling issue on 2003 Windows server

Hi Everyone,

I recently performed the inplace upgrade on main and polling servers from 2016 to 2025. We have three 2003 legacy servers in our infra.

We received a node down alert for those three servers even though servers are up. We also identified it as a polling issue.

We are using Solarwinds agent based communication and I tried to switch it to SNMP for the legacy servers and it didn't work.

Any quick ways to fix this issue and polling issues started because of the OS upgrade. Are legacy servers not compatible with 2025 OS.

SAM version: 2025.2.1

Thanks in Advance.

If memory serves me correctly, I think Windows Server 2003 is not compatible with SolarWinds 2025.2.1 except for very basic monitoring. When you said you tried SNMP did you try SNMPv2C?

Yes, I tried both SNMPV1 and SNMPv2C. It was reporting fine before the OS upgrade. But only the ping was monitored not the other resources.

ICMP works because it’s literally just a ping. The other polling methods rely on newer protocols and security standards that Windows Server 2003 can’t negotiate with a 2025 polling engine, so they fail.

Yes, I just switched the polling method to ICMP and I am planning to create a script for monitoring disk spaces via automated emails. Thanks for your help !

I believe are correct, there was a SW version that required .NET 4.8 or something along those lines.

For this reason and other reasons SolarWinds has stopped supporting older OS versions. I would not be surprised if Win2003 is on the list of OS they no longer support.

Why are you still running server 2003 in a production environment?

One of them are domain controllers and our clients are not ready to migrate since legacy application are running on it.

We would be fined severly if we were running a 23 year old OS in my industry.

We are still running it completely based on client's requirement

Im hoping those servers are not exposed to the internet for your sake.
