Q7300005: What ports do I need to open in the firewall to enable communication between the ActiveXperts Network Monitor server and the scanned servers?
The ports used when monitoring a server using ActiveXperts Network Monitor depend on the type of monitor function that is being done. For example, monitoring a web site usually requires one port – port 80, monitoring an SMTP server requires port 25, monitoring DNS requires port 53(udp).
WMI (or more correctly RPC/DCOM) uses TCP ports 135 and 445 as well
as dynamically-assigned ports above 1024. WMI is used for many Windows-based checks.
When checking which ports must be opened on the firewall, one ...

Q7300007: What ports do I need to open in the firewall to enable communication between the ActiveXperts Network Monitor server (the Engine) and the ActiveXperts Network Monitor Manager?
Communication between Network Monitor Manager (the graphical application) and the ActiveXperts Network Monitor service (the Engine) is based on a Windows share. You must allow Windows Sharing through the firewall.
Windows Sharing (or more correctly RPC/DCOM) uses TCP ports 135 and 445 as well
as dynamically-assigned ports above 1024.
The best practice is to use a packet sniffer like the Microsoft Network Monitor (installed only with the Windows 2000/2003 server) to see which ports are required....

Q7300010: Do I need to restart the ActiveXperts Network Monitor service after I've made changes to the configuration?
No; the ActiveXperts Network Monitor service automatically detects changes to the configuration and reads the new configuration in memory.

Q7300015: How can I write new monitoring checks?
Use VBScript to write your own monitoring checks.
Simply create a new monitoring check, choose 'VBScript' as the check-type, and add a new VBScript function.
Use RSH shell scripting to write custom UNIX and LINUX functions.

Q7300020: Is WMI supported?
WMI means: Windows Management Interface, and is part of the Windows 2000 operating system and higher.
It can be installed separately on Windows NT 4 machines.
WMI is an interface to all hardware and software configuration items.
ActiveXperts Network Monitor supports WMI. You can use WMI inside your VBScript monitor checks.

Q7300025: Is ADSI supported?
ADSI means: Active Directory Service Interfaces, and is part of the Windows 2000 operating system and higher. It can be installed separate on Windows NT 4 machines.
ActiveXperts Network Monitor supports ADSI. You can use ADSI inside your VBScript checks.

Q7300030: ADSI is not part of NT4. Is there a way to use ADSI for NT4 anyway?
ADSI is not included in the default setup of NT4. However, it is available as a separate product without extra costs. Click here to read all about ADSI on NT4.

Q7300035: I try to monitor a DNS server, but the 'A' record is not found. What can be the problem?
First of all, Network Monitor uses the DNS API of the Operating System.
This DNS API is only provided on Windows 2000 operating systems and higher. So, if you are using NT4, the DNS function will not work.
Second, you need to provide a proper DNS server in the DNS Setup dialog of the Network Monitor application; The DNS function does NOT use the DNS server specified by the TCP/IP properties of the OS. This would be useless, since the DNS function is often used in environments with redundant DNS ser...

Q7300070: Every Saturday at 10:00 PM, a backup of all servers in our network is made. We don't want ActiveXperts Network Monitor to send out e-mails during the backup hours. How can we accomplish this?
Just configure the 'Maintenance Hours' from the Tools menu. Select 'day of week' and choose 'Saturday'. Also enter time and duration.
All errors during this period won't be considered as a failure.

Q7300075: What is the purpose of the ActiveXperts Network Monitor Manager application?
The ActiveXperts Network Monitor Manager application can be used to configure the ActiveXperts Network Monitor service and to view results and logfiles. The ActiveXperts Network Monitor Manager application can be installed on multiple desktop PCs. Usually, all system operators will have the ActiveXperts Network Monitor Manager application installed on their PC.

Q7300085: I can monitor Windows services on some servers in my network, but not all of them. I have tried the exact same policy that worked on one server with the same service (IISAdmin), switched it over to this server and it doesn't work (it just says service not found, service = []). I have tried both description and actual service name from the registry with no luck.
Most probably, the reason for failure is: Security.
The ActiveXperts Network Monitor service requires Local Administrator rights on the server that is monitored.
To verify this, interactively log on to the Network Monitor server using the same credentials,
open a command prompt and type: 'NET USE \\<serverx>\IPC$' , where 'serverx' is the server you are monitoring. If this fails, then the problem is: security, and you have to make sure that the ActiveXperts Network Monitor service account has Lo...

Q7300090: I want to check a service on a remote computer. Should I use the 'long name' (i.e. display name) or the registry name of the service?
You can use either the short name (as it appears in the registry, in 'HKLM\System\CurrentControlSet\Services') or its display name (as it appears in the control panel). Make sure that the Network Monitor service has sufficient permissions to check the service on the remote machine. Local Admin permissions on the server you are monitoring is recommended.

Q7300105: After I installed ActiveXperts Network Monitor, the overall performance of the server decreased, and the Network Monitor software is consuming 80% of processing time. Should I add a second processor?
Most probably, one or a few checks are pulling the performance down.
It is always hard to say which one it is.
Assuming that AxNmSvc.exe is consuming all CPU, do the following:
Sort all items on 'Monitor type' from the manager, so all types of checks are grouped together.
Select all ICMP checks and disable them all. Does it make any difference for performance?
Do the same for all the other types, just like that.
Perhaps one or two checks are consuming all CPU. You should consider moni...

Q7300110: What ports do I need to open in the firewall: a) to enable communication between the monitoring client and the monitoring server, and b) between the monitoring server and the machine being monitored to allow a remote service restart on that machine?
Communication between the Manager Application and Service requires all NetBIOS and RPC ports. Monitoring requires ports that depends on the type of monitor function it uses; for instance, monitoring a web site usually requires one port, monitoring an SMTP server requires port 25, monitoring DSN requires port 53 (UDP), Best practice is to use the Network Monitor of Windows to see which ports are required.

Q7300120: In the log directory, I don't see as much entries as in the ActiveXperts Network Monitor Manager application. What's the difference between them?
The log directory only logs system state changes. For instance, when a server has been up all the time, then there will be only one entry in the log directory saying that the server is up.
The logging you see in the ActiveXperts Network Monitor Manager is different: it shows the activity of the ActiveXperts Network Monitor service.

Q7300130: Is it possible to monitor a UPS with Network Monitor? We have several APC UPS devices.
Yes it is possible. A UPS usually reports problems in the Windows Event Log. By monitoring the Windows Event Log for specific UPS events, you can receive notifications from Network Monitor when there's a problem with your UPS.

Q7300140: At various times, Network Monitor stops monitoring the checks and stops sending out notifications. On checking the state of the ActiveXperts Network Monitor service, the service apparently stopped working. What could be the reason?
Most probably, one particular check is responsible for crashing the service. There are a few known scenario's where this can happen
A mal-functioning custom VBScript program
SMTP/POP3 check: an anti-virus program interferes with the ActiveXperts Network Monitor service
SMTP e-mail notifications: an anti-virus program interferes with the ActiveXperts Network Monitor service
Database check: a mal-functioning third-party ODBC driver
Disable all notification types from the Tools->Not...
