Hi,

We have a Novell Netware 4.11 server installed here , now we went to install DHCP Server and FTP
server , we were able to load both but we are facing a poblem in DGCP Configuration , in the
subnetwork profile it shows Subnet mask to be
255.255.255.255 , but we have configured subnet mask 255.255.255.192 with INCFG , Have checked and found entries to be correct in Netinfo.cfg and tcpip.cfg . We are unable to manually change Sub net mask , we are now clue less on it.

Will appriciate help. Thanks.

remove the NIC adapter completely and reinstall it again, this time go thru Inetcfg to assign all IP and subnet mask, it will take it. Hope this helps.

And from the console prompt you performed the command

reinitialize system

?

the subnet mask indicated 255.255.255.255 translates to ff.ff.ff.ff in hex and means that server is usisng the broadcast range for you subnet. Your mask should be 255.255.255.192 which translates to ff.ff.ff.co in hex. The 192 indicates you have 62 available addresses since you throw away the network identifier of 0 and the broadcast of 255.255.255.255. I hope this helps. Ther is a website called learnto subnet.com check it out.

In the DNS/DHCP Manager throw away the current (faulty) subnet profile, and create a new one. Values in the DHCP configuration are not dependant on settings of the servers NIC's.

symptom

Cannot create new subnet profile using DHCPCFG.

When trying, it says the subnet already exists although it clearly does
not.
change

Installing dhcp server.

Recently, this is happening to pre-existing installs after applying
Support
Pack 9 (sp9)
fix

Unload DHCPSRVR.NLM, DHCPCFG.NLM and DHCPIO.NLM.
Edit the DHCPTAB file in the /etc directory. Find the name of the
subnet
profile. For example: N100_1_EII is the name of the subnet profile,
this
is
how it will look.
N100_1_EII.tc:\
:sm=255.255.255.255:\
:ht=ETHERNET_II:\
:gb=1:\
:fv=0:\
:rc=0:\
:rs=10:\
:hn:
The part that has the :sm=255.255.255.255 should be the mask that the
server
is binding to. Example
Address 10.10.10.1 Mask 255.255.255.0, this should read
:sm=255.255.255.0.
Edit the file so it has the right mask on all of the subnet profiles.
Then remove the dhcptab.lwg file or rename it to dhcptablwg.old and
also
do
the same with dhcptab.sav. Then reload DHCPCFG.NLM and configure the
subnet
profile.

Thanks...
