Peer Networking Traces
Windows Peer Networking stores local traces and state under the LocalService profile for features built on the Peer Name Resolution Protocol, Grouping, and the Peer Networking Identity Manager. This folder can accumulate diagnostic trace logs, identity and graphing state, and ESE database files such as idstore.sst and related transaction logs that support machine certificates, peer identities, and membership metadata. Kudu removes these PeerNetworking trace and state files so Windows can rebuild clean networking metadata without touching personal files, saved passwords, or application documents.
Why clean Peer Networking Traces?
- Corrupted Peer Name Resolution Protocol state in the PeerNetworking store can stop HomeGroup or legacy peer discovery from initializing, showing errors that the peer networking service cannot start
- Stale identity database files and ESE transaction logs can block creation of a new peer identity, causing repeated prompts to troubleshoot HomeGroup or messages that this computer cannot be set up
- Oversized trace logs under the LocalService profile can quietly consume disk space on the system drive, especially after repeated peer networking failures or service restarts
- Damaged graphing and membership metadata can prevent a PC from seeing other machines on the local peer network, leaving shared libraries or nearby systems missing from discovery views
- If the PeerNetworking database has inconsistent pages, the services may loop through recovery attempts at boot or login, leading to long delays before network-related features become available
- Like other ESE-backed stores, the database can suffer page fragmentation over time; rebuilding it is similar to a VACUUM in that Windows rewrites a compact copy rather than deleting rows in place, which can resolve bloated files and slow service startup
