  • 1.  DS 7.1 SP1 PXE Service Dependencies

    Posted Mar 28, 2011 11:08 AM

    Previously in DS we were supposed to run pxe_svc.vbs, which would set the dependencies of the four Symantec Boot Services and set all four to Automatic startup.

    Now in DS 7.1 SP1 I beleive we are still supposed to set the startup to Automatic, although I'm not sure where this is documented. Are the dependencies still supposed to be set somewhere, they only depend on the TCP/IP Protocal Driver, no dependencies on each other.

    I don't know where this is documented but that still seems to be the correct process.  The dependencies were created so that the services start in the correct order.  They don't actually depend on each other--because they can be started without the others running--but rather the dependencies help them to start in the correct order.

    There are still arguments about whether they are needed or not.  Personally, I still use them only because a time or two I had a problem when the services started in the wrong order, AND because I have a task I use to set up the dependencies AND the automatic, so it's a 1-click thing to get it all working right.

    However, in theory, and in very common/real practice, simply setting them up to Automatic is/should be enough.

    There is one other advantage to dependencies.  If you set them up, then when you restart the interface, ALL the services restart as well.  That's simply a right-click option saver when you're troubleshooting, so a very small thing, but since that's what I do for a living...  I like it.

    i dont remember the Kb article number, it was stated that PXE services should be start in following order:

    1. Interface

    2. Server

    3. Signal and MTFTP

    I've seen problems with malformed proxy-dhcp packets with PXE which have been resolved by configuring the dependencies with 7.0

    I was surprised not to see these dependencies configured for 7.1, as there is evidence that not having them set has caused issues with some customers. The fact that is isn't always consistent and replicable isn't in my mind a good reason to ignore it... Especially as putting the dependencies in seemed to resolve...

    I'm personally going to leave the dependencies off for now, just so I can see if this issue returns in 7.1

    Kind Regards,
    Ian./

    in 7.1 SP1 the SBSNSInterface is set to start automatic at install time. The other 3 services are set to manual and I would change them to automatic start if you use PXE.  there is no service dependency, but it might take up to 2 -3 mins after services are started for PXE to be ready.  Otherwise u could see what Ian is experimenting.
