Terminal Server running on vmware 1.0.6, getting very very slow network access.

we are running 2 physical servers as domain controllers.
Server 1 : DOmain Controller & File and Print (64 bit)
Server 2 : Domain COntroller and Exchange Server (32 bit)

Server 1 is runing VMware server 1.0.6 with Windows Server 2003 Std installed as a Terminal Server.

This has all been running fine apart from some printing issues which we have now resolved but in the last week the performance of the server has really gone down hill, logging on takes as age and we have started to see usrlogon.cmd sometime after entering logon credentials on the windows task bar for sometime, this then disapears and the screen goes blank for a significant time before showing the desktop, if we try to browse the network of connect to a mapped drive or connect to  share through run commmand the session seems to grind to a halt.

I cant explain what is happening as this has been working very well for some time until this last week. Any help will be much appreciated!

vmware network configuration is set to bridge mode. and we can ping with good results from server to server.

We have switched of our TS Group policy to make sure that nothing it that was causing the problems and still the same issue.

Hi

Are the DNS and all the network configuration good??

Seams like a DNS issue.

Check the DNS from the servers that are taking to long to logon. Test you AD from and to the Domain GC from the server itself.

Hi Jail,

DNS is fine on the network all tested and ad working with no problems, it is only on the Terminal Server in VMWare these issues are occuring.

How many VM's are running on the VM Server?  Was a new one added recently?

What is the CPU/Memory usage of the host OS?

How is the host connected to the network?  Single NIC, dual NIC's in a NIC team?

My personal opinion:  Terminal server is a VERY CPU and memory intensive server process.  Unless you have a powerful physical, or this is a test environment, you should not be running terminal server under a VM.   VM's are for environments were you can put a lot of low usage server environments on a single physical server and share hardware resources.  Terminal server is typically not considered a low usage server function.

The server is a Dell Poweredge 2900 dual Xeon 2.0GHz Processors with 8GB memory, currently the server runs as DC and File server only so CPU and mem usage is hardly anything.

It is running currently with one NIC enabled at 1Gbit speed

The server is only running single Windows Server 2003 Std as Terminal Server.

How many users do you have using the term serv.  Based on my limited experience with terminal server, the physical server would be the minimum requirements just to run term serv.

Um, let me get this straight.  The physical server is a dual Xeon box with 8 GB of memory.

It is running Windows as the host OS and the host OS is also your DC and does file sharing?
Then you have one VM that is a terminal server?

How much memory have you allocated for the terminal server VM?

What is the memory usage on the host OS?

We have now been advised by VMware to upgrade the version of VMware server to latest version 2.0, we had backed up virtual hard disks and updated vmware server. All working fine now!!!!!

Thanks for your help on this one but vmWare to the rescue after 10 days!!!

I am having a similar performance issue. Are your NICs Broadcom? I hear tons of rants on these cards. I am about to put an Intel 1000MT card in the server to see if it runs better.

Good luck.

I found many notes on the broadcom cards that stated disabling Large Send Offload and Checksum Offload at the Broadcom NIC (at the host) will help with many network performance issues.
