SNMP Status unknown in solarwinds

Hi All,

We are having some discrepancy in solarwinds regarding SNMP status for windows nodes. We are getting the SNMP status as unknown in SolarWinds for windows nodes but when we give SNMP test for it there is no issues. It passes the SNMP test. Will this affect the nodes from throwing alert ? What are the possible ways in bringing back the nodes UP from the unknown state ..
