Network Information Service (NIS) Server
nis-srv is a legitimate NIS server component. It centralizes user, host, and map data for network clients using ypserv-like protocols and distributes updated maps to registered slaves.
nis-srv is the executable component of a Network Information Service (NIS) server that centralizes user, host, netgroup, and passwd-like maps for network clients. It runs as a background service, answering ypserv/ypbind requests, distributing maps to registered clients and supporting consistent authentication across systems. This service is essential in environments that rely on centralized identities and host naming.
nis-srv operates with a master/slave map architecture, serving maps such as passwd, hosts, and group to clients via the NIS protocol. It relies on map databases that can be updated centrally and replicated, with appropriate firewall and rpc-bind configurations.
Quick Fact: NIS was designed to simplify network management in mixed UNIX/Linux environments by providing a single source of truth for identities and host information.
Yes, nis-srv is safe when obtained from trusted vendors and deployed with proper access controls and secure configuration.
The real nis-srv is not a virus. Malware can disguise itself with similar names; verify the path and signature.
C:\Program Files\NetInfo\nis-srv\nis-srv.exe or C:\Program Files (x86)\NetInfo\nis-srv\nis-srv.exe. Any nis-srv.exe elsewhere is suspicious.Red Flags: If nis-srv.exe is found outside: C:\Program Files\NetInfo\nis-srv\ or C:\Program Files (x86)\NetInfo\nis-srv\, runs when no network service is expected, has no valid signature, or uses excessive resources, scan your system.
nis-srv runs as a background service to provide centralized directory information to network clients. It orchestrates map distribution and reply handling for NIS protocol requests.
Reasons it's running:
Yes, you can disable nis-srv. Stopping it will disrupt network identity lookups for clients until it is re-enabled. Uninstalling will remove the service and may require alternative directory services.
If nis-srv is consuming excessive resources or failing to respond, you may need to inspect maps, replication, and network configuration.
Quick Fixes:
1. Quick Fixes:
2. 1. Check which maps are being requested with client logs or monitoring
3. 2. Verify master/slave relationships and map checksums
4. 3. Review firewall rules for NIS ports
5. 4. Ensure maps are up to date on master
6. 5. Restart nis-srv service if needed
nis-srv is a legitimate NIS server component when obtained from trusted sources and configured with proper access controls. Verify the path C:\Program Files\NetInfo\nis-srv\nis-srv.exe and a valid signature.
nis-srv is safe to run in networks that rely on centralized identity management. Always verify vendor and signature before deployment.
Yes, you can uninstall NetInfo NIS Server via Settings -> Apps. This will remove the service and data unless you back up your maps.
You can restart the service from Services.msc or using net stop/net start commands. In some environments use a Management Console to control the service.
Disabling nis-srv will stop map lookups for clients and may cause authentication failures for network users until re-enabled.
To update maps, modify the master maps and trigger a replication; then verify slave servers receive the changes and clients fetch updated data.
