NetHasp License Problems

[ILv2Rk]

We have a NetHasp License and have had nothing but problems with the client machine being disconnected from the server. this happens 5-10 times per day. We have tried everything that our reseller has said but had no luck. Just wondering if anyone else has had this problem and overcame it.

what are you running for OS on license server? Best on XP Pro or Server 2003. Also best to be setup to run as a service.

[ILv2Rk]

yes, OS is XP and we are running as service

[Bullines]

How many licenses are on that NetHASP server?

[ILv2Rk]

Our License includes:

2-Mill Level 3

1-Lathe Level 1

2-5 Axis Mill

[Bullines]

Is that computer used for anything else? What I'm really getting at is the 10-incoming-connection limit that Windows XP Pro has (it's 5 connections for XP Home).

 

So for example, the NetHASP server is an XP Home computer. Let's say four people check out Mastercam licenses. And then somebody else, not using Mastercam, accesses files in a shared folder on that NetHASP server computer, 5 connections are used up. Now when a fifth person tries to check out a Mastercam license, they can't. Although you still have a remaining Mastercam license, you've maxed out your connections to that XP Home box.

[ILv2Rk]

This computer is only used for running one seat of MC and the NetHasp Server

[Bullines]

In that case, do either of the computers lose network connectivity throughout the day? Or is it just the NetHASP? Is the Windows Firewall, or some other software firewall, enabled on the NetHASP server and/or the client?

[ILv2Rk]

To explain further,

 

We can have MC open and running on the client machine and then a message will pop up saying "Sim has become disconnected and Mastercam will now close. You will get one chance to save your work. sorry for this inconvienience."

When this happens there is no apparent reason. The Server machine did not reboot or shut down.

We have tried giving the server a static IP address and then editing the .ini file to aim at that address and also changing the timeout to "0". still no luck

[ILv2Rk]

windows firewall is enabled but we have created an exception for mastercam to get through on port 475

[ILv2Rk]

No other network loss on either computer

[Bullines]

Does your nethasp.ini look something like this?

 

code:

---

[NH_COMMON]

 

NH_TCPIP = Enabled

 

 

[NH_TCPIP]

 

NH_SERVER_ADDR = 192.168.1.20 ; or whatever your server's IP is

NH_PORT_NUMBER = 475

NH_TCPIP_METHOD = TCP

NH_USE_BROADCAST = Disabled

---

I'd avoid setting NH_SESSION and NH_SEND_RCV for the time being.

When this happens, are you able to ping the NetHASP server from the client computer while that dialog is displayed?

[ILv2Rk]

Yes, nethasp.ini looks like that.

 

I don't know if you can ping the server while the message is displayed, i will have to try it.

 

What are you thinking that will tell us?

Just want to be certain that the connection between the client and the server, regardless of the socket needed to keep the NetHASP connection alive, exists. Yes, you can ping. The "Sim has become disconnected" dialog is modal, so at that point before you click "OK" to dismiss the dialog, you should be able to fire up a command prompt on the client computer so you can try to ping the server.

[ILv2Rk]

Thanks Bullines, I'll try thatthe next time I lose connection with the NetHasp server and I'll let you know the outcome.

It will probably happen again today, it has already happened 4x and it's only 2:00.

[ILv2Rk]

Well it just happened again and the answer is yes, i can ping the server with the message up

[ILv2Rk]

Our IT guy said he wondered if it could be a problem if anyone on the network was running internet radio and hogging bandwidth?

 

Would that make a difference?

[Bullines]

I wouldn't think that radio would be an issue. NetHASP uses very little bandwidth. Is this wireless? Also, do you have any other apps on your LAN using TCP port 475? When this disconnection happens, the NetHASP service on the server continues to run, right?

[ILv2Rk]

The server has a wireless connection to the internet but it was also happening b4 the wireless connection.

No other apps using port 475.

NetHasp continues to run on the server when a disconnection happens on the client machine.

So what you're saying is that the server has 2 network cards; one wired and one wireless?

[ILv2Rk]

No just a wireless.

We just got new screamin' computers which have the wireless connection, (this is where the server resides), and our old computers have hard-wire network cards

[Bullines]

So it isn't a case of your wifi connection dropping out, then, right?

[ILv2Rk]

No, because it was happening b4 on the old hard-wire system.

We have tried switching around the server to different machines and still the same problems.

[Bullines]

In your Windows Firewall exceptions lists, do you have both TCP 475 and UDP 475?

[ILv2Rk]

Only TCP 475, do we need the other one also?
