Using ON Command software while using Intel Boot Agent ver 4.0.19, the client aborts on unattended installs of a client OS. The error message reads:
"PXE-T02 access violation, PXE-E3c, tftp error access violation."
Certain types of DHCP servers may supply boot file names that are not terminated in a null character. Intel Architecture Labs PXE 2.1 addresses the null-terminated boot file names, but fails to work correctly if the DHCP boot file size option is not present when using Intel Boot Agent 4.0.19.
This issue has been corrected in Intel Boot Agent 4.0.22. Customers using IBA 4.0.19 and running into this issue can also work around it by setting DHCP boot file size tag 13 as a nonzero value (ideally the size of the boot file).
This issue can also be caused by an incorrect path in a DHCP server's Scope option 067 Bootfile Name. Ensure that the path is "\etc\integra\tftp\boot.ovl" (without the drive letter assignment).
