Issue Description

user's topology: clinet pc---switch---router---swtich---server
When the client accesses the server, http service is normal, but SQL server service is abnormal.

Alarm Information

Null

Handling Process

On the router deny 1433 ACL is configured. So SQL service cannot be used. Delete ACL and the service recovers.

Root Cause

Anable ACL on the router and the matching relation of ACL and windows is as follows:
135=Location Service
137=NETBIOS Name Service
138=NETBIOS Datagram Service
139=NETBIOS Session Service
445=Microsoft-DS
593=Unassigned IPC Server
1023=Reserved
1025=Reserved
1068=Installation Bootstrap Proto. Cli.
1433=Microsoft-SQL-Server
1434=Microsoft-SQL-Monitor
2784=world wide web-development

Suggestions

If one service is abnormal and other service is normal, configrm the problem according to matching relation of ACL and windows.
