Were you a regular reader of these forums, you would know that the Ghost developer team were laid off a couple of years ago and development of GSS 3.0 was stopped. Even before that, the level of funding provided to the development team precluded many enhancements to the product. So there is no ongoing product development and only very limited bug fixing from the team in India, who also have a very restricted budget. Patches are available to those who are experiencing specific problems and who have a maintenance agreement. These patches are strictly aimed at specific bugs that affect some users so are not going to address any driver version issues. There are three patches - 2269, 2298 and 2605 and you can find out the specific issues they address by searching on those numbers in this forum. As you have service contracts - call up support on the number given in the sticky posting at the top of this forum and discuss whether any of the patches are relevant to the issues you are experiencing.
Trust me - you are not making anything more public than it already is.
HOWEVER. Windows 7 is supported so although Win 7 SP1 may not be officially supported, I see no reason why it should not work as the servicepack is not changing the basic functionality or design of the operating system. If you have SPECIFIC issues, please share them with us.
New Intel Pro 1000 cards - when you say they are not supported, have you tried adding the Vista 32 bit drivers to Ghost Boot Wizard? Users do indeed have problems with new NIC hardware, but since the underlying operating system using these drivers is MICROSOFT's WinPE, the problems usually turn out to be in finding the correct driver downloads. New NIC chipsets are being released all the time so sourcing and adding new drivers is not an unusual requirement. Basically, if you can install Vista on the new hardware and get it working, then there is no reason why WinPE should not work just as well.
General problems with Deploy Anywhere - what sort of problems are you seeing? As with WinPE, Deploy Anywhere also needs the relevant drivers to be present, albeit this time appropriate for the target operating system. Once again, the provisioning of drivers follows Microsoft procedures - If you look at past postings by Nigel Bree you will find detailed explanations of how it all works (Nigel is a former Ghost developer).
Problems with changing IP addresses - can you clariffy what problems you are seeing? I recall no threads in recent times which suggest any issues with IP addressing - assuming the NIC driver is correct and is not defaulting to 127.0.0.1 as it cannot contact the DHCP server.
Driver updates through LiveUpdate - you will not see anything new on LiveUpdate as mentioned earlier, as there is no ongoing development.
Also, you will not be sent anything by posting here, as this is a user forum and only tech support can supply you with patches. If you have support agreements, then you can get them from support.
