The exact error message I receive regarding user authentication is "The user name or password specified is not correct. Provide new credentials."The only article regarding this error should not involve any problems with IIS.
Did you try logging in as a LANDesk Administrator on a share on the Core? Does that connect?
Yes, I am able to connect and write to the LANDesk shares just fine. I made multiple changes to the boot.wim file yesterday and replaced the new version over the network. The new boot.wim shouldn't be the issue because provisioning runs fine on certain ports.
Regarding the LANDesk shares, are any files being transferred to or edited on the core during the the provisioning process? (besides I assume it is writing to the LDLog share)
Not sure if you're still having this problem, but I experienced something similar after updating to LD9 SP3. I wasn't able to map any network drives, so all of my provisioning templates would fail. The error said it was a bad username or password, but I knew that wasn't the case. The solution to my problem was inputting the following line to the end of the all.reg file in the WinPE image:
I found the info for this fix at the following site:
It looks like WinPE 3.0 may have some issues authenticating to shares on a domain where the DCs aren't on Server 2008. In any case, it worked for me, hope it helps.
