comment Why does chkdsk take a long time on one particular index?
I don't believe that the Index Service uses an NTFS index (and I already tried turning it off IIRC). It can't be a HDD issue because the data was moved to a new HDD without changing the results. I now suspect that this is simply an artifact of the way chkdsk handles rigorous index checking; for example, it may be loading as much metadata as it can into memory and then processing it. The issue goes away if you use the /I switch.

comment Any difference between DOMAIN\username and username@domain.local?
Also, "it won't use the username to verify if it is allowed in the ACL but it will use the SID" is the expected behaviour - it should always do that, regardless of whether you use domain\username or username@domain. Are you talking about a case where there are two domains with the same name, or something similarly pathological?

comment Any difference between DOMAIN\username and username@domain.local?
-1. I really can't follow what you're saying here. Where you say "When the users will connect to the server" which server do you mean, the old DC01, or the new DC01? What happened to the old DC01 anyway, was it decommissioned, renamed, removed from the domain, or what? Was it properly demoted first? What do you mean by "new domain", since you didn't describe the creation of a new domain at any point? If you use "domain\username" it should always search the domain you explicitly specified, are you describing a case where it doesn't?

comment PXE Boot an ISO with iSCSI information
That's odd; it should take about the same time to boot WinPE either way. Are you sure you're measuring the total boot time from powerup to ready?

comment PXE Boot an ISO with iSCSI information
I assume you've tried using the boot to WinPE ISO option with the same ISO you burnt to CD? Do you know how netboot/i presents the information to WinPE when you choose the boot to CD option? Would it be possible to set up the iSCSI hard disk to boot the netboot/i WinPE.wim and use the iSCSI boot option?

comment Does changing a Service from Automatic to Manual mean that it is unable to be started by other services/applications?
If the services were configured as Automatic by default there is probably a reason. If you configured them as Automatic it should be safe to change them back. Basically you need to look at the documentation for each of the services in question.

comment Replacing .dll files while the application is running?
@Shadur: actually, the reason you can upgrade libraries while in in UNIX is that the file system allows you to unlink a file while an application is using it; the file remains on disk until it is closed, but there is no directory entry pointing to it. There are advantages to that approach, but also disadvantages.

comment Windows AD: difference between “net use … /user:” as mere mortal or domain-admin?
If the domain admin user already had a connection to any share on the server, perhaps one reestablished automatically from a previous session, the /user flag will be ignored.

comment Replacing .dll files while the application is running?
Depending on the software in question, it might be possible to install and run two or more distinct instances (in different locations). Inefficient, but perhaps workable.

comment Replacing .dll files while the application is running?
In my experience, in most cases (well, more than half the time, at any rate) you can rename (but not delete) a DLL without any tinkering with the application.

comment What does it mean to grant/set permissions for NETWORK SERVICE on a network share?
@Chris: no, that's not right. There's only one NETWORK SERVICE, not one per machine, and it is only valid locally. If you grant access to NETWORK SERVICE on \\MyFileServer\MyShare, that will allow services running on MyFileServer in the NETWORK SERVICE context to access the share. It will not give access to services running on any other machine on the network. It does not matter which machine you use to change the permissions. To give access to services on MachineA, select MYDOMAIN\MachineA$. In the GUI, use the Object Types option to allow you to select a computer account.

Just because you can do something, it does not logically follow that it is ever useful to do so. (Although in this particular example, there may be a few edge cases.)

comment Domain Admin RDP access
Also check the "allow log on locally" and "access this computer from the network" settings. IIRC, both are required for RDP access.

comment Domain Admin RDP access
Have you looked at the security logs? Can domain administrators log in at the console?
