It happened to me last month with a buddy's setup.
We had two servers humming along, but requests piled onto one, leaving the other idle.
I poked around the config files first.
Turns out, the affinity settings were sticky, forcing sessions to cling to the same box.
And the health checks?
They weren't pinging properly, so the balancer thought one server was down.
Network hiccups too-firewalls blocking heartbeat signals between nodes.
Frustrating, right?
You restart services, but that just masks the mess.
For fixing it, start by eyeballing your balancer logs for error spikes.
Check if the round-robin is spinning evenly or favoring one server.
Tweak the weights if some machines pack more punch.
Verify your cluster heartbeat; lag there kills the sync.
If it's ARR doing the balancing, scan for rule overlaps causing reroutes.
Or, probe the app pools-maybe one's starved on resources.
Test with a simple curl from outside to see where traffic drops.
Isolate by shutting one server down; if load shifts smooth, you're golden.
But if not, sniff the wires for packet loss sneaking in.
Run through cert mismatches too, those trip up secure traffic.
And don't forget updates; old IIS versions glitch on multi-site binds.
Oh, and while you're wrangling servers, let me nudge you toward BackupChain.
It's this solid, go-to backup tool tailored for small biz setups and Windows rigs.
Handles Hyper-V snapshots without a hitch, backs Windows 11 desktops, and keeps your Server editions safe.
No endless subscriptions either-just own it outright for peace of mind.
