OOo2.0rc1 and nfs

I'm having a problem with OOo-2.0rc1 and one of my computers. I have a home network with NIS authentication and shared home directories via nfs. I just installed OOo-2.0rc1 and find it works well, except one machine OOo-2.0rc1 cannot read or write documents over nfs *on this one machine only*. OOo-2.0rc1 can browse the nfs mounted filesystem, see the filenames, but fails with "General input-output error accessing whatever.file" when I try to open them. If I copy these files to a local filesystem, this exact same installation of OOo-2.0rc1 on the very same machine can open, read, write, save, whatever with no problems. But over nfs it cannot. My other linux machines (Xandros-3.0.2-OCE, kernel 2.6.11; Fedora Core 1, kernel 2.4.29) with OOo-2.0rc1 installed from the same downloaded package can read-write-open-save-whatever over nfs and locally. And OOo-1.1.5 running on the problematic machine can read-write-open-save-whatever over nfs as well, even with the same files OOo-2.0rc1 refuses to deal with on the same machine at the same time.

Vectorlinux -- problematic machine -- is slackware based, but since OOo-2.0rc1 is only avauilable as a package of rpms I installed using rpm.

Xandros-3.0.2-OCE is Debian based, but once again I used rpm to install -- but it worked here.

Fedora Core 1 is rpm based and worked fine as well.

Any ideas?
