SYMPTOMS
When you attempt to change the string value of the sysContact, sysName, and sysLocation objects using an SNMP manager (such as the Hewlett Packard OpenView), the following error message appears:

SNMP error - sysContact read only (OV3122)



CAUSE
The Windows NT 3.5 SNMP agent only allows read access for the sysContact, sysName, and sysLocation objects. According to Internet MIB-II definition in RFC 1158, these SNMP objects should allow read and write access as follows:

  sysContact  OBJECT-TYPE

SYNTAX DisplayString (SIZE (0..255)) ACCESS read-write STATUS mandatory DESCRIPTION "The textual identification of the contact person for this              managed node, together with information how to contact this               person." ::= { system 4 }

sysName    OBJECT-TYPE

SYNTAX DisplayString (SIZE (0..255)) ACCESS read-write STATUS mandatory DESCRIPTION "An administratively-assigned name for this managed node.              By convention, this is the node's fully-qualified domain               name." ::= { system 5 }

sysLocation OBJECT-TYPE

SYNTAX DisplayString (SIZE (0..255)) ACCESS read-write STATUS mandatory DESCRIPTION "The physical location of this node (e.g., 'telephone              closet, 3rd floor')." ::= { system 6 }
