Network problem

Hi - I am having problems sending Apple Mail to my SMTP server - it hangs and sometimes drops before delivery.
I thought there might be a conflict with P4 so as a troubleshooting move I switched off the P4 Host-only and shared adapters in my apple network prefs.

Yet I am still able to connect to the internet via P4.

How can this be?

help, please

tia

Hello,

a) On windows side click on start - > control panel - > add/remove programs - > from here
remove the Parallels tools completely. Shut down Windows properly,restart the Mac.

b) After restarting Launch Parallels Desktop - > configure - > install Parallels Tools.
Now Parallels Tools will be automatically installed.

After installing Parallels Tools - :

1. Go to System Preferences - > Sharing - > Internet and turn off Apple Internet sharing.
2. Please set Parallels Network Adapter to Shared networking.
3. In Windows please open Network Connections -> right-click LAN icon -> find Local Area
Connection properties -> select Internet Protocol
TCP/IP properties -> open General Tab and select Obtain IP and DNS server addresses
automatically check boxes.

Now please have check whether you are connecting to internet from windows side.
 
thanks Srinivasulu.V

done

no.

the 'configure' menu does not mention Parallels Tools
I had to launch Windows, and then got an alert telling me to install Parallels tools from the Virtual Machines menu.
First I got the 'Install New Hardware' Wizard - which then told me 'Cannot Install this Hardware' ( could not find the necessary software). I then chose 'Finish'. The Wizard kept coming back, so I chose 'Cancel' the next time.

I then installed the Tools and XP relaunched.

> 1. Go to System Preferences - > Sharing - > Internet and turn off Apple Internet sharing.

it was off already, and is off now

> 2. Please set Parallels Network Adapter to Shared networking.

it was already set, and is set now.

> 3. In Windows please open Network Connections -> right-click LAN icon -> find Local Area
> Connection properties -> select Internet Protocol

all done

> Now please have check whether you are connecting to internet from windows side.

yes, I am.

However, if I select menu/devices/Network Adaptor1/Disconnect then I can't get on the internet.
menu/devices/Network Adaptor1/Shared gets me back on again.

Hi,
Was the problem with smtp resolved after deleting the adapters from network prefs?

About second part of the question, the Shared Networking of Parallels Desktop 4.0 really may work when adapters are disabled or deleted from preferences. Some of the use-cases are not available if they are disabled, but generally networking really works.

Did you advise me to delete the adapters? Perhaps I missed a post?

I don't understand the second paragraph, can you state it differently?

eg. what is a 'use-case'?
how does networking really work if the parallels adapters are turned off or deleted?

does this mean that parallels is alway live on the network even when the adapters are turned off?

If so, what are the adapters for?

Is P4 networking always active even when P4 is inactive?

cheers

Nope, I don't advise this. My question was related to info in your first posting:

Although I think that this info may confuse even more then my previous posting, here is the technical info -)

When these Parallels Adapters are disable, VM can't communicate from host. But it is still able to communicate with Parallels Networking Daemon, which will do all networking for VM. This Parallels Networking Daemon doesn't use any complicated mechanic and can't create any trouble.

No. I hope that my prev. paragraph slightly clarifies all three questions.

PS: Actually, we are planning to remove these adapters from Network Prefs. in one of the next releases of Parallels

thx elric :-)

slightly clarified but...

if Parallels Networking Daemon does all the networking for VM and the Adapters are irrelevant ( although they must remain installed for now), and the VM can still negotiate the internet despite the Adaptors, and you are planning to get rid of the Adaptors, at what point in the history of Parallels did they become functionally redundant, and will the planned change mean that I cannot kill VM networking from the Host side?

I hope I have demonstrated that I understand what you've told me, and that my questions make sense :-)

Hi Peter,

Actually, the thing is complicated...

The only thing that I can state, is that if Parallels Adapters are disabled (or not present) in the Network Preferences and no VM is running, the Parallels Desktop has no influence to Host networking.

The Parallels Desktop is able to work whith networking even if the adapters are disabled or not present in Network Preferences since 4.0.3810
 
thanks Elric - I'm getting clearer.

However, I am still concerned that the VM is connecting to my router/modem as a distinct entity without me being able to turn it off from the host side
